About Heintz Art Metal. In 1906 Otto L. Heintz invented and patented a secret method of attaching decorative sterling silver overlay to each piece without the use of messy solder. The silver overlay is decidedly Arts & Crafts in the hand craftsmanship it required and the depiction of natural motifs, such as flowers, plants, leaves, birds and branches. Heintz would go on to patent his processes for producing articles in metal, most notably his unique method for applying sterling silver to bronze without solder which was granted in 1912. Deco pattern with an Art Nouveau style, making it a unique and ornate decorative collectible. The rectangular frame is suitable for a 2 x 3 inch photo, with a top-loading photo insertion type for easy display.

Frank Lloyd Wright was inspired and influenced by Otto Heintz and commissioned numerous pieces for himself and for other projects.
