Found this fun 1962 Quaker Life magazine ad of the forgotten cereal mascot the Useful Protein. You'll see that I added another scan of the ad and this one is for anyone who would like to cut him out. I used a card stock type of paper to print him on and after cutting him out he now stands next to my computer monitor.
JUST CLICK ON THE SCAN AND PRINT HIM OUT FOR YOUR VERY OWN USEFUL PROTEIN
If you want a smaller one just use this smaller version to print out.
