While I have always believed that there were two separate issues of Bond Bread cards, Rounded corners 1947 and squared corners 1949. I read this somewhere, that 1949 was the second issue for the cards. But does anyone know where the date for 1949 comes from for the squared corners cards?
To add to my confusion, now there seems that the rounded corners cards were issued in 1947 by Bond Bread as a 48 card set, and the squared cornered were issued in 1947 by Bond Homogenize Bread, in a 24 card set.
Are they the same company? Have I been wrong in believing that the two issues of Bond Bread were 1947 and 1949?
Were they two different sets issued in 1947, one set of 48 cards rounded corners from Bond Bread? And another set of 24 squared corners and printed on thinner stock, (paper) from Bond Homogenize Bread.
Who was issued in each set and is there a checklist for each? And are they different images on the cards?
I will not even get into the 1980s squared cards.
