And/Or Press, 1980. Softcover. Unpaginated, circa 24 pp. 28 x 22 cm. Text in English. Used VG+. Original vintage calendar published by iconic and nice And/or Press. As in the past years, their purpose was to show the marihuana flower in as much detail as possible through these close up vintage photos. This year dedicated exclusively to Sinsemilla. By the way, very fine close up studio photos that show off its beauty and complexity. The world of vintage calendars is amazing, and in any case, this Cannabis Calendar is just one more push to getting high like only as it was done in the past, but without forgetting when the sun enters Pisces, a relevant information and vital important ;)
