Antique 19th century child’s Milk Whistle Cup

Pre-20th century children’s “milk whistle” mug. Features an idyllic hand painted scene of a boy and a girl fishing, and a working, whistling bird mug, signed with initials “SL” on lower left side of painting. Beautiful condition, fully functional bird whistle on handle. Amazing condition, one very faint crack visible by the handle, otherwise flawless.
