Pulps have not had the benefit of a Gerber Photo Journal book. Thusly, most are undiscovered. I see ones every day I never knew existed. Pulps have breathed a lot of new life in my collecting endeavors.
I have known for years that they are much more rare than comics. Very few people had the forsight to amass large collections in high grades. Comics have many pedigrees, pulps as of now, do not.
In knowing all of this, I have always known that the time to buy one you like is when you see it. Might never again get the chance. There are so many cool ones in all genres. But, they will always be second fiddle to comics for me.
