You are looking at a painting by Sir Edwin Landseer showing the famous American lion tamer Isaac Van Amburgh coaxing the fierce and large lion to lie down with the lamb as the highlight of his London circus act. This performance was Queen Victoria's favorite and she often took her family to the London circus.

The potters did many circus figures because the posters served as wonderful source material, so here you see the VanAmburgh performance translated into pottery!  These seated lions are almost a foot tall and you can see the little lambs lying at the lions' feet.  Produced in the late 1840s the pair is $5995.
