The third print poster, an authorized reprint, is blue on the back of the poster, and the "#17" has been added to the "Wes Wilson '66" printing credit.  This poster measures approx.  14" x 20", and was probably printed in 1967 or 1968.

The original handbill, printed prior to the shows on very thin paper, measures approx. 5 1/2" x 8 1/2".  Unlike most of the early Fillmore images, BG 17 was not reprinted as a postcard.  If you are collecting the Fillmore "small" images, the original handbill is the only option on the BG 17.
