This was included in assorted paperwork that came with my recently purchased SD convertible. It was blown up and printed oversize, 11" x 17" on glossy paper. My best guess is that some prior owner had access to an original price list, such as dealers would have had to show to customers, and made the copy. Note the old-time typewriter that was used to prepare it originally. There was some water damage on my copy, that I fixed with a little copy&paste. Wish we could have those prices again, eh?
