Three huge margins just in at bottom, full Shermack perfs at sides, rich color, wavy-line cancel, trivial tiny internal paper break adjacent to a Shermack perforation (completely unnoticeable, not mentioned in either cert and possibly from the Shermack perforation itself), choice Fine appearance (photo). $50,000
