Congratulations, Eddie, on the Marhoefer Meat cards pick-up.  Even I have heard of these tough-to-get racing cards.  There's a guy in Columbia City, Indiana that deals in a lot of the post-war regional / food cards.  Off-hand, I cannot recall his name, but he knows very well of how much racing collectors cherish these cards---by the impressive prices I seem to remember him charging!
 
No different than the baseball card collectors obsessed with the "free prizes" in, or on, hot dog packages.
 
Have a great weekend, my friend.  Again, congrats on the pick-up, especially the A. J. Foyt.  One of my favorite models I own is the IXO 1/43 diecast of the 1967 Ford Mark IV that AJ shared with Dan Gurney to win the 24 Hours of Le Mans.  Great race, great-looking car, great driver pairing--and the only time they were paired together.
