You might call Antique Electronic Supply in Arizona. They don't list posters in their catalog, but they buy huge lots of discontinued tube stocks, perhaps there are catalog covers, books and display materials they would be willing to sell.
For sheer beauty, Mosaic Records has limited edition prints in black and white of some of the most gifted jazz musicians of our time. These are hand made photographic prints and fairly expensive. I expect they will increase in value over time. Link to their site provided below.
