My Dad, With Buoys

My dad, Jac La Tour, grew up near place in Wisconsin called Moose Lake.  His dad, Clifford La Tour, was an occasional inventor.  One of Clifford's most promising inventions was a buoy for lakes.  He enlisted my dad and his brother Richard to help manufacture these buoys.  Recently, my dad was getting rid of some old photographs, and I asked to look at them.  They were pictures of my dad with the buoys, and I liked them so much, I took them and scanned them.  Here they are.  My dad, with buoys:
