This poster was released at the 1999 Macworld Expo in San Francisco. I personally picked this poster up when I was there, it has been rolled and kept in climate-controlled storage for over 2 decades. I have another listing for this same poster that has thumb tack holes in the corners, but note that THIS POSTER DOES NOT have any holes, tape, folds or rips. The poster is 24 x 36 inches, and is made with heavy, thick, paper. Not a reproduction or counterfeit.A great piece of Apple history, great for any collector or enthusiast of Apple! I have many other collectible posters and Apple memorabilia - see my other auctions!
