I buy every reasonably priced card of my cousins that I find.
That has resulted in a stash of 37 examples of the 1940 Play Ball Lee Handley #221, 23 examples of the #33/34 1941 Double Play Handley/Vaughan, and approximately 10 or so each of the 1952 and 1953 Mothers Cookies Gene Handley cards.
It started as an initiative to provide my children with their own cards one day, but no, I do not have more than 20-30 children, so I really don't know where this is going, --but it has become rather impulsive.
