I really wanted the illustrated item but sadly I undervalued it in my
ebay bidding. While I have several interesting First Lady free franks I don't chase them generally but with most things philatelic, if I have not seen it before I often try to purchase it when I do.
Free franks are commonly found it two versions, actually signed and with preprinted signature. This item, for me, expanded the version to three. It is the first metered printed signature I have seen. I trust there are others from Mrs. Eisenhower. Perhaps some members here can show metered free franks from other first ladies, former presidents or other with a free frank privileged.
Note the auxiliary marking which was added by I don't know who, the sender or the USPS.
