The Antikamnia (Opposed to Pain) Chemical Company of St. Louis, Missouri produced several calendars (1897-1901) illiustrated with Skeleton Sketches--chromolithographed series based on watercolors by the local physician-artist Louis Crucius. The limited edition calendars were mailed to physicians who provided business cards or letterhead correspondence as evidence of their medical standing. Antikamnia was a proprietary product consisting of acetanalid (antifebrin) combined with sodium bicarbonate, citric acid and caffeine.

The Liebeskind Collection recently acquired a copy of the calendar for 1899, which matches 2006's calendar day-for-day.

A downloadable copy of the 1899 calendar is available, below. Click on each image to see a high resolution PDF image which may be printed or copied.
