Seen online (but lost out on the bidding):
This is an example of the Beauclaire Rose appear on a pre-Beauclaire card!
The brand name Beauclaire does not appear in print until 1951. Before this time, cards of buttons appeared with the border as seen above. Some of these cards were labelled “A G.P. Product.” This design was one of their most popular, presumably, as it appeared in many variations right up into the 1980s.
