These postcards, most of which measure 4" by 5" and are in black and white and are blank-backed, feature members of the 1961 Minnesota Twins, the first year they were in Minnesota. These cards have black and white photograph along with a fascimile autograph. A couple of cards measure 5" by 4" instead. Since these cards are not numbered, we have sequenced them in alphabetical order. Some collectors refer to these as the type 1 postcards for the Twins.
