First two are each 1.5" with enamel initials standing for Columbia Boat Club. In addition is an enamel flag at center with initials "NAAO." Each is dated on the front for 1916 but they differ by the engraving on the reverse which on the first is "Double Skulls" and on the second "4 Oared Race." These once hung from fabric ribbons now gone. Minor tarnish on the sterling finish. Third item is also sterling with engraved text on back "Canoe Tilting." This also once hung from a ribbon. Front shows man with oar in canoe plus man swimming beneath text "Pittsburgh Press Meet." Additional text is "Lake Elizabeth June 16, 1917."

Next two are from same sponsor "Pittsburgh Press" but these still have their complete but worn fabric ribbon badges with bar pin on the back. Each shows a diver and a man in a canoe.
