If you are a lover of BMW (and other auto..) art, there is a site that I subscribe to (for furniture ideas mostly) that is like a high-end ebay, called 1stDibs.com. Currently there is a collection of beautiful watercolors, that includes a 327 vert and a 502...Item number on the 327 is.....LU101017302132. Located in Poland. Fair and negotiable prices. I sent a note to ensure that its original art, not a print, and was told it was all original art. No affiliation, just an FYI..
Sorry that I'm not much of a computer guy to post the images, they are excellent.
