Uncommonly large mattable vintage blue ballpoint pen signature on a 5x8-inch tan sheet, folded twice and mailed to inveterate collector David R. Smith in the 1960s. Beyond the aforementioned folds, neither of which passes through the autograph itself, in good condition, with glue remnants to all four corners on the verso, from previous mounting in a scrapbook.
