I just got back from the local baseball card show and this is one of the cards I found.
In the middle of all the autograph, relic and refractor cards was an older couple who had some of these old Wheaties panels.
I'm not really sure if I can call them cards because they are huge. Originally, theses panels would be cut off the side of the cereal box. And from what I understand they practically took up the entire back of the box.
This example is numbered No.16 of a series of 16 and is of Dolph Camilli, the Brooklyn Dodgers entry in the set. Each team, there were only 16 in 1938, had a player represented.
I was really surprised to see this type of card at a local 20-table show. I usually have to go to a regional-type show to find this sort of thing. I was also surprised to see quite a few vintage cards.
I even found a few poor old baseball cards. Stay tuned, I'll be posting them in the coming weeks.
