This Grueby tile measures nearly 1" thick, by 4" square.  It has a classic boxy squared form glazed in a simple mat blue glaze, with controlled curdling, very even, as shown in the photos. This simple tile is beautifully marked with the Lotus flower incised mark, along with the words Grueby Tile Boston, guaranteed to be vintage Grueby, c1902-1905 period.  It is in near original factory condition, with just minor handling wear, and a couple of corner nicks/chips. It is a nice example of Grueby's simple mat glazes and it presents quite handsomely.
