This one has the Interpace TV Screen backstamp which was used from 1971 until 1976.  When Interpace bought the company, they started putting the year in the backstamp.  

So, with this piece we can determine that it was in fact made in 1972.

With all my pieces when I bring them home, I hand wash them. 

I do this because I don’t believe you can truly say there is “no crazing” without getting them wet.  Crazing can hide.

 So, when I say there are no chips, cracks, crazing or repairs, I have done my due diligence to discover any defects.
