Simons Bros. Sterling Silver Thimble with Country Scene, Size 12 (#19)

Simons Bros of Philadelphia, PA was founded in 1839 by George Washington Simons, at that time, they were manufacturers of gold and silver thimbles and pencil cases.  The company grew rapidly from there, expanding to include many gold and silver items including (!) tooth and ear picks, earrings and finger rings.  The sun is rising above the mountains, there is a farmhouse and a fenced road.  How did they get such detail on a thimble??  There are no punctures and it is not out of round.
