What is the size of Georges Rouault's painting The Old King?

According to Gardener’s Art Through the
Ages (edition 10)page 1036, George Rouault’s painting The Old
King is 30.25in x 21.25in.

Rouault was a French
Fauvist painter which meant that he used extremely bright colors and simplified
designs.  Rouault worked as a glass maker before he started painting; consequently his
work was very influenced by a certain stained glass window aesthetic.  He often used
thick black outlines around areas of bold color, referencing the power and prominence of
medieval stained glass.  This technique is exemplified in The Old
King creating an iconic feeling of authority around the kingly figure in the
painting.
