Advertising Postcard: 1898 Callard and Bowsers Butterscotch, Ducks Manufacturers added credence to their products by obtaining royal warrants, medals or, in the case of Callard and Bowser, gaining testimony from The Lancet, who said of their butterscotch, "Really wholesome confectionery" This is a brand new and unused glossy finish postcard. Part of the British Nostalgia range, this postcard is a high quality reproduction of a familiar advertisement or advertising poster from the past, and shows a fascinating insight into British life over the last 100 years. My eBay ID doesn't of course appear on the actual cards! Postcard measures 4.25 x 6 inches.
