Neat postcards. I collect them. Not sure if I understand the question, if there is one? If it is, has anyone seen them before, for me the answer is no. But there are millions of postcards of baseball teams so new ones (that I haven't seen or don't remember seeing) pop up every day. I like the backs too!!

ps...btw what size are these? They don't have postcard backs....though I have some "blank backed" postcards and these, depending on size, certainly might be like those..
