I was scanning some 6x7 B&W negs today. I'm actually trying to see if my new printer will print BW as well as advertised. If it does, I may sell my wet lab. My wife wants the room and I could buy some new equipment.
But the point of this post is to see who (if anyone) can guess what this really is. So look it over. If you can figure it out first, you get a prize! Enjoy.
