If you collect vintage basketball cards I highly recommend that you check out my new site. It contains probably the most information on pre-1970 basketball cards available on the internet. I think right now I only have about 70 issues posted, but that number will increase as I put more time towards it.
Welcome aboard! You've got some great information on your site! Also, you might be interested to know that I've got a very rare George Mikan advertising display from the late 1940s. The version I have is the original promo used by Miller Brewing and was obtained from a former executive with the company. As far as I know, it is unique and was never distributed publicly. If I get a chance, I'll post an image of it.
