I came across these interesting and fascinating Antikamnia marketing calendars from the late 19th century at Unique Auctions, who are selling three at their auction on the 5th April. The Antikamnia company marketed a pain relieving powder to pharmacists and druggists of the late 19th and early 20th using these morbib but fascinating calendars.

Each Antikamnia Calendars features 6 pages each detailing two months of the year with wonderful images of mischievous skeletons. The art and imagery is exceptional and on researching prices it seems that are interest to collectors which some calendars selling for hundreds of pounds.
