These two images are from a stereoscopic set-up also invented in 1838 according to Wikipedia. One image has been flopped. I'm no expert and yet I was able to figure this out after a cursory glance and a little help from photoshop. Sorry Ivan, I don't think you've got Abe after all, nice picture though.
