Well, after a seemingly neverending trip up and down the east coast, Roberto's 1957 Topps blank back has found a new home.
I can't thank Michael (Empty77) enough for his generosity. As I told him, it is the most generous gift I have ever received on Net54. He was a class act all the way through, even when the card seemed to be delivered to the wrong address at one point. It all worked out and I am ecstatic to add him to the collection.
Thanks again Michael!!!
