Different 19th century child's mugs for different reasons--though made for children, these always feel quite loaded in one way or another, and here the all caps urgent "WARNING" feels very timely indeed. Also a reminder that, as much as we might like to imagine otherwise, most childhoods were never carefree.
2 11/16" d x 2 3/4" t. 3 1/2" across at handle. Very very good antique condition, no chips, cracks or other issues, just a few imperfections native to it. Transfer decoration with hand-painted color, c. mid 19th century.
