Security envelope stars

It was a pleasant surprise to find this envelope security pattern of four-pointed diamond-shaped polygons.   

 

Are 4 points a star?

 

The repeating pattern itself is very small; repeated it grows massively.

 

Security envelope patterns come in different patterns that .  Usually, they are small and tightly packed, covering the whole interior of the envelope to obfuscate the contents.

Now called by another name

This cross hatched manhole cover is seen in the street beneath our feet.  The company identity oval interrupts the orderly layout of the "=", "-", and "|" elements that are used in the design of this utility cover.  

 

Originally called the United Electric Power Company, the name was changed to that seen on the manhole cover on November 30, 1927.  This cover would have been produced some time after that.
