Rare Flying Jenny Comic Pinback from the collection of Hud Baer

This pinback was issued by Overbrook High School in Philadelphia.  The class of Feb 1942 had chosen Flying Jenny from the comic strip of the same name drawn by Russell Keaton to be their class mascot.  Issuing pinbacks showing a class mascot was a Philadelphia High School tradition.  This is one of the very few pinacks known to show Flying Jenny.  Anyone having information about class mascots chosen by other Philadelphia High Schools is encouraged to comment.
