I have started and developed three faceBook sites, first, starting with cards ending at 1970. Than I had to start a memorabilia site to keep the card guys happy. As time went on I started a third sit for NY Highlander collectors like myself. All three are doing well.

The card and memorabilia site there is tons of buying and selling, but the Highlander site it’s more of a show & tell site, a friendly place to visit. As my collection grew I found the only place I could find collectors like myself is on Net 54. I want my Chesbros and Keelers the gang mostly wants Mantles and Berras. Net 54 has it all, the main hangout.
I am a disabled man and these sites are a good part of my day !
