A printer’s proof is basically the same as an artist’s proof except that there are even fewer of them produced. They provide an even more exclusive opportunity for a collector to own something very unique, as they are given to the printer or publisher by the artist. Traditionally, printer’s proof edition sizes are very small. At visiblevibrations, we only sell ORIGINAL Concert Posters, Art Prints, Music Memorabilia and Limited Edition Art Toys!
