Description
Following the arrest of leading underground figure John ‘Hoppy’ Hopkins for possession of cannabis, Steve Abrams (& others) organised a ‘Legalise Pot Rally’ in London’s Hyde Park in July 1967.
A couple of posters were produced in relation to the event. Click link below.
SOMA Steve Abrams “Times Advertisement” newspaper Poster

Martin Sharp’s also produced posters for both the 1967 & 1968 rallies, the 2nd was also used as the cover for OZ Magazine #13.

I’m aware of a few variations of this poster. The main two are both printed on foil :with/ without the address at the bottom.The production of this poster led to Peter Ledeboer setting up Big O posters. Supposedly the posters without the address were printed for fly posting around London, and the batches with ‘BO1 Cannabis by Martin Sharp Published by Big O Posters Ltd 219 Eversleigh Road’ at the bottom were for retail at head shop or mail order.
