This attractive small mug measures about 3" x 3". It was made by the firm of Samuel & John Rathbone, Tunstall, Staffordshire, between 1812 and 1835. It features a Chinese building and a curtain-draped pavilion on one side, and a grouping of three people and a dog on the other. The pattern is illustrated on page 60 of Ian Harvey's book, "Rathbone China Manufacturers Tunstall, Staffordshire".
The pattern was made in both earthenware and porcelain. This is the porcelain version. The transferware print has been painted over with enamels. (Sometimes called clobbering.)
The mug is in excellent condition. There are no chips, crazing, or repairs. I cannot see or feel any cracks. There is some discoloration of the interior base.
The base is marked with Rathbone's "R" surrounded by a sunburst. This mark was formerly (and erroneously) attributed to William Ratcliffe. The pattern number "10" is handpainted on the base.
