Graded vintage concert posters are big business — but may not be as pricey as you might think (gallery)

Vintage concert posters can be big, big business with iconic artists’ psychedelic promotions of the 1960s a particular focus for many.

CGC, which is known for grading comic books, also grades concert posters, handbills and postcards, helping collectors weed out bad examples of posters and helps show the elite pieces on a 10-point scale.

One major dealer of these pieces, the Baltimore-based Psychedelic Art Exchange, recently completed an auction with many pieces that commanded good amounts of cold, hard cash — but may not have sold for as much as you might think.
