This yearbook is from 1966 Baldwin High School in Pittsburgh Pennsylvania. It was owned by 2 brothers, Tom and John.  Their friends and teachers signed it.  It might be Tom and John Ludwig, class of 67, based on the content of the friend's notes.  The brothers were cross country state champions in 1965 and are in the Baldwin hall-of-famers for swimming.    The cover is embossed with the title and possibly the mascot. The cover at the spine has some wear and a spot where it looks something caused the cover to punch inward thru the cover but I don't see damage in the inside from that.  

Book stand not included.
