I went to the Musee Mechanique in San Francisco to see the vintage player pianos in person, and while I was there I got these photos of historical Americana.
To snarf the raw photos, head over to my Flickr cache. As always with my work, these are under a Creative Commons (Attribution Share-Alike) license to enable people to reuse them. Personally I plan to attach them to MP3s to serve as album art.
