What's the most memorable card you acquired when opening a pack?
The best birthday present I ever received was when my brother gave me a box of unopened 1969 Topps baseball. One pack I opened and got the #500 Mantle. And then got another Mantle from the same box! Still have both and received one back signed (in ballpoint) : from Mantle in around 1970-71 sent to his home in Dallas when hardly anyone sent requests to home addresses because you couldn't find them.
