The bubble log is for "EMU".  University in Michigan.  They chanced their mascot in 1991 to an eagle.

Right from an estate sale.

CONDITION:  Nice condition.  The bubble logo is really nice.  Ink is dry.  Some light signs of age on pen.

I HAVE MANY VINTAGE PENS FOR SALE INCLUDING MORE BUBBLE PENS.  PLEASE SEE MY OTHER LISTINGS AS I WILL DISCOUNT AND COMBINE SHIPPING IF YOU BUY MORE THAN ONE AT A TIME.
