I have been trying my best to get my son interested/involved in the hobby but being 15, he has other things on his mind it seems?
That aside, I have told him/shown him my Mantle, Mays and Robison cards as well as a few of my other high 52 Topps numbered cards just so he is familiar with/knows them so hopefully that carries over some day where he either adds to my collection or at least cherishes them and does the same with his children someday.
Times change but I believe it is up to us adults/parents to do the best we can do to help keep these players, and the hobby, as active/known the best we can.
