The Nimble Nicks postcards were probably made between 1915 and the early 1920s. Three of the Nimble Nicks postcards shown here are dated 1916.
Whitney postcards are usually referred to as "Whitney Made" because of the Whitney Made/Worcester Massachusetts postcard logo on the back of the card. The majority of Whitney Made postcards are lightly embossed and feature cute children. The postcards were manufactured in the United states, mostly somewhat later than the imported holiday postcards that were popular during the postcard fad years before World War I.
