Vintage men's tie bar/clasp from the 1950's - 1960's manufactured and signed by SWANK. Gold tone metal with slide rule and glass bubble magnifier that slides back and forth! Condition is excellent; there are very tiny imperfections on the gold tone bar underneath the slide rule piece that moves. Clasp is secure; tie bar measures approximately 1 3/4 inches long. The perfect gift for the math or science wizard or Mad Men fan who loves retro stuff and ties.
