Puzzle Nuts and Bolts

Definitely out of place on my photostream, lol, but thought I'd add this photo (macro) of a Nuts and Bolts puzzle that I picked up from the Lee Valley Tools store three days ago. Maybe an inch and a half tall. "All" you have to do is remove both bolts, which, of course, is harder than it looks. Would make a neat "stocking stuffer." I have collected metal (and other) puzzles for many years and actually have a small wall in my hallway covered in copper wire puzzles, which look quite attractive.
