Classic psychedelic image, featuring a photo of the Grateful Dead, which has been artfully worked into the psychedelia.  A classic Conklin piece.

The original/first print poster measures approx.  14" x 21", and was printed on glossy stock.  A script "W" does not appear after "MUSIC" in the lower right corner of this poster.

The second print poster, an authorized reprint, is identical in size and paper stock to the first print.  A script "W" appears after "MUSIC" in the lower right corner of this poster.

The original postcard was printed prior to the shows, and measures approx. 4 1/2" x 7".  Two variations exist as follows:

Type A  Place stamp here back
Type B  Calendar of events back

A double postcard of this image and BG 163 was also printed.  It measures approx.  7" x 9 1/4".  Most of these were mailed.

It is worth noting that the cards were not printed on the same glossy paper stock as the posters.  They were printed on an uncoated index stock.
