After much debate , the 73rd Annual TPSA Convention & Trade Show was cancelled this year for the safety of attendees , exhibitors and staff . Though this decision was not easy to make , the TPSA Board of Directors thanks you for your understanding and looks forward to seeing you all next year at the 74th Annual TPSA Convention & Trade Show . In lieu of having our event this year , let ' s take a trip down memory lane and remember conventions past .
