Beauclaire advertised its ‘Tiny Tots’ button in 1954. They included a rabbit, elephant, fish and a duck that previously been sold under the Norris C. Rex label. The elephant was for some reason left out of the advertising below, although it did appear on a leaflet included in a dress pattern.
However, they also sold them on there standard cards, as seen above. They can be spotted within 1954-55 advertising.
These designs have been intermittently reissued ever since, so have been a long term success story. Even today Spotlight stores are selling a “new” novelty duck that is the same design.
