The body of this earthenware mug is a pale green/gray "putty" color, and the aesthetic design transfer is in deep blue/gray. Motifs include butterfly, floral and a geometric/framed landscape. Typical of the fad for Japanesque motifs in the 19th century. Only mark is a printed square on base, which may be a fragment of a mark or simply a stray piece of transfer. Probably English, and judging by the design of the mug and transfer, I would date this circa 1875.
Size: Approximately 3.125" high.
Condition: Excellent, with only some minor interior and bottom staining. Stray piece of clay fired on base rim during manufacture. No chips, cracks or repairs.
Note that I try to be conservative about condition descriptions, carefully noting any flaws. Of course, with antique items, there will be some signs of usage, and/or manufacturing defects. But overall, my customers have always been pleasantly surprised upon receiving their items, and of course, Returns are no problem if I happen to miss anything.
