Some really great research Charlie Brown and Mike.
But, as you probably know, the Jackie Robinson card shown here (with the Berra, Hodges, Kiner, Musial, and Thomson) was indeed inserted in 1947 BOND BREAD packages.
I never thought (as your research indicates) that any of the 13 cards in the Jackie Robinson BOND BREAD set were inserted in the bread packages. And, I say this because
I remember very well that in the Summer of '47....my sister and I carefully opened up Homogenized Bond Bread packages, for the regular BOND BREAD cards (48-card set).
Our Mom could not buy enough of the Bond Bread loafs. So, we convinced our Dad to buy Bond Bread for his restaurant, so we could get more of these B/W cards of BB
players (and the 4 cards of the Boxing Champions) for our collection.
Neither did I see, nor heard from my cousins, friends, etc. who also collected these 1947 BOND BREAD cards ever getting any of the 13 - Jackie Robinson cards in his set.
