bgar3, is this it? It is from 1912, they are in suits, and it has facsimile autographs. It was really tough to locate, but ended up finding it listed on eBay (so you can buy it back if you want). Great memory you have, as it does have the distinctive "E." Not sure how well the rest of it matches up, but when his wife signed for him she didn't use that "E." So being from 1912, it does add to the mystery:
