A card that was located with the effects of Edward Everett Wilcox.
The opposite side of the card has a list of names (perhaps friends from an evening together?). Those listed lived in the neighborhood of the Wilcox family in Winchester, TN (ca 1870); most located on census records.
Another card - or what's left of it - with a scribbled note, including "Main St." (one of the places the family lived). It appears to be addressed (probably by Edward) to "Papa," but most of the writing it difficult to decipher.
More notes and cards, including a business card for E.E. Wilcox who apparently used the name "Edwin" on a few documents (though he had abandoned that for his legal name, Edward, by the time he moved from Tennessee to Texas).
