Wallet Card at the Sozodont Toothpaste sign

Like most cities, New York has a lot of old painted advertising signs on the sides of old buildings. This one for Sozodont toothpaste has been on this building on Vanderbilt Avenue and 43rd Street for over a century; for most of that time it was hidden by a neighboring building. That building was recently torn down, exposing this relic that advertised a toothpaste brand briefly popular in the late nineteenth century. (It's popularity faded in the early 1900s as its high alcohol content destroyed enamel and turned teeth yellow.) Unfortunately this ad will not exist for much longer; over the next few months all of the buildings on this block are being torn down, to be replaced by a generic glass office tower.
