This carte de visite photograph of a single boot was taken at the studio of William Foss Shorey. Shorey’s studio is known to have been located at 105 W. Baltimore Street during the late 1860s.
Why a boot? The most likely explanation is that a boot-maker wished to advertise the quality of his wares.
This boot resembles the “Enlisted Men’s Boot” now handcrafted by Robert Land Footwear for the Civil War reenactment market.
I have not been able to make sense of the faint lettering at the bottom front and on the reverse.
