A unique signed, limited edition silkscreen of John Van Hamersveld's classic Velvet Underground concert poster. Van Hamersveld originally created this artwork in 1968 for a poster to advertise a concert by the Velvet Underground and Chambers Brothers at LA's Shrine Auditorium.(br)In the 1980's he produced a signed, numbered limited edition of this artwork with LA publisher L'Imagerie. These were hand silkscreened, and printed on 23 1/2" x 33" art paper–much larger than the original poster.(br)In the 90's I purchased a number of these from Van Hamersveld's ex wife, and mixed in were a few signed with "TP" written in the right corner. TP means 'Trial proof;' these are proofs with the same printing elements as those in the edition. However, they deviate from the edition through a sequence or color variance, or through added or deleted elements as in the trial proof. A trial proof may have been pulled at any time during the proofing period or during the printing of the edition. They are signed if the artist feels they are a unique and desirable variation. There is often an overlap in intent between trial proof and the color trial proof.(br)This one-of-a-kind trial proof has been signed by Van Hamersveld, and denoted as a CTP in the bottom left hand corner in pencil, by him. It has the "L'Imagerie" embossed edition stamp in the left bottom corner as well. This is a one-of-a-kind proof.(br)We guarantee this to be authentic, without time limit.
