I used to be a very pro-active RPGA member here in the UK at end of the 90s - I volunteered as a GM then acted on behalf of the RPGA UK - as a Area Coordinator - then promoted to a Regional Director helping promote the RPGA in schools and clubs and assisting at Conventions around the world - during this time I was allowed use TSR stationery - whilst moving some more boxes around I came across the last of them.. all unused

TSR letter manila Envelope (a4 sized)
TSR letter manila Compliment slip (standard compliment size)
TSR letter labels  (4 per page)
