I have a pretty substantial overall NBA collection, around 70 or 80 signed jerseys, balls and shoes. Every member of the Top 50 except Maravich, and then another 20 or so greats that have come along since -- LeBron, Kobe, Duncan, KG, etc etc.
In terms of Lakers stuff, I have jerseys signed by Kobe, Shaq, Magic, Kareem, West and Baylor, shoes signed by Worthy and balls signed by Pau and Mikan. I already have a jersey and shoes signed by LeBron so I doubt I'll be getting anything more, although Upper Deck already has some Lakers stuff up and it's tempting. I only wish I had more space to display everything.
This was pretty weird: There's a dealer out in So Cal that I got some stuff through when I was in full-bore amass mode who offered to sell me one of George Mikan's prosthetic legs. I passed.
