Lovely old transferware milk jug, marked England's W Dean - Burslem
(Staffordshire) Royal Semi China (semi porcelain) Forget Me Not. The
color here is a deep aqua, not quite green, not quite blue.
The pitcher stands about 5 1/4" tall. It's in very good condition without chips or cracks, foxing stains only to the bottoms of the 'feet' as shown.
