Hi Everyone,
Last week there was a photo on Ebay that looked like it had the potential to show what the Shavano drumhead looked like, so I bid and won it. It arrived earlier this week, and I just had the time to scan it. Here is the image;
The white on the left side appears to be steam vapor rising from the steam line. It appears to be a canyon, with a river in the lower right disappearing behind a bluff on the left. This certainly doesn't show up as well in photos as the image in the San Juan drumhead did!
The trick would be to find another shot that would match this and other images that have been posted. Perhaps an Otto Roach or George Beam shot?
