What You Need to Know Before Hunting Down Justice League Of America 1
It depends entirely which one you mean, because there are several numbered first issues of Justice League of America. That is the single most confusing thing about this title and it will trip up almost anyone who tries to collect or read it without checking first. The original Justice League of America #1 came out in November 1960 with art by Mike Sekowsky and a story by Gardner Fox. This is the issue where the team gets a proper origin retelling, the Hall of Justice gets established, and it kicks off what became the flagship DC superhero ensemble book. It sold for twelve cents. A near-mint copy will run you somewhere in the eight to fifteen thousand dollar range depending on CGC grading. That is not a typo. I have seen 9.8 copies sell for well over twelve grand at auction, and I have also seen the same issue in fair condition go for less than two hundred at estate sales. The variance is insane. Then there is Justice League of America Vol 2 #1 from 2006, which was the George Perez and Jimmy Palmiotti relaunch that followed the Infinite Crisis event. That one is still available through standard comic retailers and DC Direct. It is affordable and reprints are common. If you just want to read the story, this is the version that makes sense for most people.
There is also Justice League: The New 52 #1 from 2011, which some people colloquially refer to when they say "JLA #1" even though the numbering is technically different. I need to flag this distinction because you will see it pop up constantly in searches and on resale sites, and it causes confusion. If you are looking for a free PDF or digital download of the 1960 issue, those exist on archive sites but they are scan quality at best, often missing pages or rotated wrong, and they violate copyright. I am not going to link to anything like that. The 2006 and 2011 versions are available legally through DC Universe Infinite, ComiXology, and the usual digital comic platforms at a standard subscription or per-issue price. I spent about three hours once trying to track down a specific copy of the 1960 #1 for a friend who wanted a graded copy for an insurance appraisal. The problem was that Heritage Auctions and ComicConnect were both listing copies with different pedigree information, and one of them turned out to have been relabeled with a fake pedigree to inflate the price. I ended up verifying the CGC certification number directly against the Census database and caught it before the purchase went through. That is a thing that happens regularly with high-value silver age issues. Always verify the certification number yourself. Do not trust the listing description.
The storytelling in the original 1960 issue is straightforward silver age fare. The JLA gets assembled, fights a bunch of classic villains including a combined effort against the Joker and Lex Luthor, and establishes the team dynamics that would define the book for decades. It is historically significant more than it is narratively brilliant. Read it if you care about comic history. It is fine if you do not. For the 2006 relaunch, the premise is simpler. Superman is missing, the team is scrambling, and Wonder Woman and Flash take charge while Batman pieces together what happened. It is a solid entry point for someone who wants to read JLA without committing to sixty-five years of continuity. The art by Perez is clean and professional, though some readers find it a little too polished and lacking in edge. That is a common critique and fair enough. One thing people miss when they start with JLA is that the numbering has jumped around because of cancellations and relaunches. Volume 1 ran from 1960 to 1987. Volume 2 started in 2006 and ran to 2011. Then the New 52 rebooted things again. If you are building a collection or reading in order, you need to decide which volume you are tracking and stick with it. Mixing volumes without understanding the publishing history will leave you confused about why certain character appearances do not line up chronologically.
Get the Full Details
My suggestion depends on what you want. If you want to read a good first issue of Justice League without spending money, go to DC Universe Infinite and pull the 2006 Vol 2 #1. If you want the historically significant copy and have the budget, look for a CGC-graded 1960 #1 and verify every detail before buying. If you just need a summary of what happens in either version, I can write that out too, but you probably should just read the damn comic.
