Large (2-7/8") Incolay belt buckle features a large 3-masted Clipper ship. Incolay buckles were manufactured in California by the Incolay Co. No two are exactly alike. Each is signed on the front.
Belts with buckles like this one held up many a pair of hip-huggers during my college days in the early 1970s! This one has some visible wear on the back; the front is in excellent condition.
