Quaker Cereal 70's internal use magnets Tony Tiger Cap'n Crunch 75 total RARE!

Description

From an estate sale, this is a set of 75 magnets from a Quaker Oats executive.  It looks like they were used for tracking sales and distribution, or perhaps production.  There seem to be magnets for each variation of size a cereal was sold in, and sometimes different art or prize offers on the front.  The cereals there are magnets for are:
Cap'n Crunch
Frosted Flakes
Cheerios
Grape Nuts
Post Raisin Bran
Frosted Mini-Wheats
Special K
Corn Bran
100% Bran
Quaker 100% Natural Cereal (3 varieties)
Shredded Wheat
40% Bran Flakes
Life
Total
All-Bran
Quaker Puffed Wheat
Rice Chex
I think that's all of them?  They're all in the pictures.  Magnets are very small, but fun to see so much art from about 1977.
Thanks for looking!  Any questions, please ask.
