Vintage Tile Architectural Block Easter Bunny in a Flower Garden

This massive architectural fragment makes a great display piece. The molded and multi-colored glazed block shows a rabbit sitting in profile in a grassy garden. A large flower is in the background. This 8" x 8 1/4" block tapers towards the front image to 7 3/4" square. I suppose to keep this 12 pound block from slipping out and bonking someone on the head. However, this makes it display well on a shelf.  Unsigned, this was attributed to California Art Tile (1922-1956) by the Rago Gallery, where it was purchased in the 1990's. Impressed on the edge is "DB 81". Light traces of mortar and a sizable chip on the lower right, only noticeable when viewed from the side.
