OK, time to pick your brains. I just acquired some magazines from the late 60's/early 70's; In here I am finding several ad's with Bill 'Grumpy' Jenkins. Some of them are full page ad's (like this one from Fram) and others are smaller (say 4 1/2" x 5"). Are these considered sought after? If so what type of value do they hold. Trying to determine if I should try adn sell them or just hold on to them for the 'conversation piece' factor.
