Vintage, Early, H&R Johnson, Greece, Philkeram Johnson 6" Tile Blue Red Tulips

Very early 6" x 6" H & R Johnson raised glaze art tile. It's marked 'Made in Greece by Philkeran Johnson'. This piece hung on a kitchen wall at an estate in northern Nevada hence the discoloration on the back. The non-glazed porous ceramic really absorbed the elements. The hook is affixed with hot glue. Can be removed and replaced (or not) by new owner if desired. Please see photos. Thanks for looking!
