Vintage 1969 NOS Harley Davidson Dealership Advertisement with Corporate Letter For Sale

An amazing piece of history. Unused are two dealership-issued 1969 Harley Davidson clear window displays for their 'Out Performers' campaign. This campaign was a large introduction to their AMF era, as the ad campaign featured the 900cc ironhead Sportster, the Electra Glide, and the 350cc Sprint. Great item for collectors, enthusiasts, and those looking for a special motorcycle Harley art piece. Museum worthy piece, archival. There are TWO 36"x60" polyflex posters and the original typewriter letter from the Harley corporate office. 3 total pieces. Dated and signed with instructions on how to place the ad. The letter is just as valuable as the posters in my opinion.
Please do not hesitate with questions. Will mail in a cardboard tube. Can provide more photos on request, tough to capture as it is a clear poster.
