These late 1940s-early 1950s cards are approx 12.5 x 19mm, and carried 1-2 dozen buttons. An advert from the time shows one of these large Beutron cards.
Beutron yellow “All Purpose” cards were marketed from 1949 until 1960. The price of 1 shilling 3 pence dated from October 1951-March 1952, then from April 1954 until June 1957. The baby card appeared in print during 1957.
This late 1970s card of buttons is a good example of how fashion buttons have been made to mimic livery/uniform designs, with a crown that looks like a Guelphic Crown, also known as Prince Albert’s crown, as it was the crown of the Dukes of the House of Hanover.
Beutron supplied buttons for Lincraft. These presumably are intended for a tennis outfit, probably from the late 1980s.
