We get these kind of posters all the time at work, what I have learn to look for is condition vs. popularlity of the band in comparsion to the date. What I mean is these poster were made to be used on poles and sometimes in cases. Original ones will usually show wear from use, this is more the case with posters from early concerts, cause for the most part they were not popular enough to be collected. In this case Cream started in 1966, this one dated 1968, would be a early poster if real and very few could be found in this condition, but it is possible. Now you do have Eric Clapton who was already famous from the yardbirds, so there is a better chance of someone getting a unused one or one from a case and putting it away. The next thing is fading from it being displayed on the wall from a avid fan, and of course smoked colored from well the room filled with smoke, cause only a young rebel would even snag one from the party room. Basically the point being very few of these poster will have no signs of wear, and if it looks too good well it probably is, cause every head shop in town has a few repo's hanging around, for us older folks to hang on the wall to remember those great times of the late 60's and 70's.
