If it is on the outside of the cellophane, it was added after the printing process. I don't know what H. R. Sticker you are referring to, but I assume it is something that the Roosevelt added once they got their cards. Definitely the same edition, but I don't think that most people would consider it a different variant because it wasn't created that way. There may be some market for collectors who want to get every single variation of a deck, regardless of who created the variation, but not sure. I suppose the only way to find out is to check out existing sales, or try to sell your own.
