There's a cemetery in Castine, Maine, a lovely coastal town perhaps best known for Maine Maritime Academy and a surviving crop of stately old American elms, with headstones dating back into the 18th century -- the standard old headstone shape, often topped by winged skulls. Thanks to a local historical society volunteer, I got my hands on a couple rubbings; these show a particular style of stonecarving that proved captivating to the point of typeface design. Castine has a full character set in both roman and italic styles.
