This is a Montgomery Wards Hawthorne ladies bicycle.  This bicycle is of a medium size (17") and should fit most women from about 5'2" to about 5'7" or so.  This one will need a tune and has a slight bend to the frame.  A can of pledge, some steel wool, and a few rags and you would get a decent bike out of it.  Tires hold air and the coaster brake stops fairly well. 

Its not perfect, and will need a tune to get it to decent...

don't forget about the slight twist in the frame.  Also the top tube (twin bars) have a broken weld where they meet the seat tube.  JB weld won't fix that.

Measurements:

Seat Tube 17"
