I'm coming to Philly this summer and would like to find a couple of old store signs to photograph for the family history I am writing. They are... Unity-Frankford Abbotts Dairies (or Abbotts Ice Cream) Williams Restaurant (in Frankford) Greens Cafeteria (downtown) They can be either actual signs, photographs of signs, or just printed logos. Any suggestions would be welcomed and appreciated. Larry B.
