Psychedelic and fantasy art weren't the only subjects that were used for blacklight posters in the 1960s and 1970s. This 23" x 35" example of a monster poster was discovered on eBay. The title is "Monstrous" and it is dated 1971 by "Scrutiny". The multi-colored image is printed on thick stock paper with a velvet/flocked texture finish. The "buy now" asking price is $85.85.
