Leon --
Thanks for posting that awesome Burdick letter to Wagner and the announcement of the US Card Collectors Catalog, which I think you've posted before. I don't see Burdick thanking Wagner for a T206 Wagner in that letter (he thanks him for four unspecified cards, including a Pontifical Standard), but he did thank Wagner for donating a T206 Wagner in the October 1, 1948 CCB, which I posted last week in the "Burdick Collection, 1947-49" thread:
