Rare GRUEBY Arts & Crafts 5-color Bird Tile

A strong GRUEBY arts & crafts, five-color architectural tile . Only minor blemishes (rubs, crazing) on an almost massive, 6" x 9" highly decorative tile. Back is just a bit rough from apparent mounting. Rare, one of a pair (if you can find the other) of facing birds; the alternate is chiefly white as opposed to this bold multicolor piece. A charming bird. Provenance, one of the East Coast major pottery dealers.
