This is one of the classic psychedelic images, made even more popular by the appearance of the Grateful Dead.  Due to the combination of the inks and paper that were used to print the original posters and cards for these shows, many are prone to noticeable fading.  In many cases the light blue of these items appears gray, or even white.

The original/first print poster was printed on vellum paper stock (soft to the touch...matching the paper stock used to print the original cards), and measures approx.  13 5/8" X 22".  This is 3/8" shorter than the second print poster.

The second print poster, an authorized reprint, was printed on uncoated index stock (smooth to the touch...identical to the stock used to print Fillmore originals from mid 1967 through 1968, which is when this poster was printed), and measures approx. 13 5/8" X 22 3/8".  No cards are known to exist that were printed on the same paper stock as the second print poster.

The original postcard was printed prior to the shows, and measures approx.  4 5/8" X 7 3/4".  It has a place stamp here reverse.

A double postcard was printed of this image and BG 52 (prior to the shows).  It was the first double image card that was printed by Bill Graham, and some were actually mailed.
