Coming and Going is based on Charley Harper's larger illustration, 'Once There Was a Field,' created in 1974 to accompany an article of the same name published in Ranger Rick. Motawi tiles are made with a custom mix of clays and pressed from original plaster molds. Every tile is hand-glazed and embossed on the back for authenticity. At approximately 5/8 inches thick, every tile has a notch in the back for hanging unframed. Made in the USA. To clean, wipe with a damp cloth using mild soap. Ceramic. Measures 6 x 6 in.
