|Variant of||Association San Francisco 1966 (OP-1A)|
|Notes||1st printing posters have three sub-variations due mostly to a variety of paper stock which they were printed upon. |
On all, the lettering of "Wes Wilson '66" is in dark red that matches that of the ticket outlet strip. Paper thicknesses are all at or under 0.008"
The 1C variant is on 0.0075" > 0.0080" stock with no glow under black light.
