Here's an "End of Day" sewer tile sculpture that recently sold on eBay for $ 789.00.
Sewer tile was made primarily between 1880 and around 1930 and usually only produced in the Northeast. Workers in the tile plants would use left over clay and glazing materials to produce small whimseys like this one.
Makers mark on botton, inscribed "OLD FIZEAK." 6" high and 5.5" inches wide.
