Delicately Rendered 1880s Pennsylvania Folk Ink and Watercolor Ledger Drawing of Native American Chief (Copy)

This is my favorite drawing I've had in some time, just the sort I go to Pennsylvania (and everywhere else) hoping to find. I know that it dates to right around 1880, and came from a ledger held by a young Burt Gemberling of Selinsgrove, Snyder County, MA. (Makes me think a bit of the drawings of Wayne Blouch, which I presented in an online viewing room in collaboration with Ricco Maresca a few years ago) Such a wonderful grace and delicacy to the ink drawin details, with just a bit of watercolor for the face. I am loathe to let this one go. 

12 7/8" x 7 3/4". Beautiful condition, black ink and watercolor on laid paper.
