Patent medicine vendors began to take out advertising space in almanacs in the 1820s and began producing their own in the 1840s.
By the time of the Civil War all of the major patent medicines were publishing their own almanacs and the numbers are staggering; for example, the Ayers company was printing 15,000,000 almanacs annuay and in 21 languages!
Below are scans from one of the wartime almanacs in my collection, produced by A.L. Scovill & Co. for 1864. More wartime almanacs from my collection are forthcoming. Enjoy!
1) The front cover - notice that this almanac was produced exclusively for New York and New England. See the hole punched in the top right-hand corner? It served a very important purpose: a small piece of string or hook could be attached and the almanac could be hung in the home, or more likely: the outhouse!
2) The back cover - note the variety number of medicines produced by the Scoville company! No less than nine different cures! Apparently this almanac also carried the imprint of a Stamford, CT general store.
4) A new addition for many almanacs in the Civil War years was a chronology of the war up to that time.
