We receive thousands of requests to authenticate posters every year and in most cases the information is available on our website. If you just purchased a Woodstock poster, a Radio City Music Hall poster or something similar, please look it up on our site first. In many cases you will find the information there that will allow you to tell the difference.
Unfortunately, we do not have the time or resources to respond to every request to authenticate posters purchased on eBay, Craigslist, garage sales and flea markets. As a result, we no longer authenticate or render opinions on posters purchased elsewhere.
2) The Grateful Dead Radio City Music Hall poster. Unfortunately, these are difficult to tell apart unless you are very familiar with them. Our best advice is to only purchase these from a very knowledgeable dealer who will guarantee the authenticity.
4) The AOR 3.116 Hawaiian Aoxomoxoa second print poster bootleg. Virtually every one of these we see is fake, including those sold by somewhat knowledgeable dealers. Here is the link for the information on these: http://www.classicposters.com/Grateful_Dead/poster/Art_of_Rock/3.116
