B.S. Black widow decal

I have an old decal with a black widow spider on it and the letters B.S. What company was this?

 

A pic would be nice.

 

B S = Bomb Squadron Black Widow B25C of the 345th Bomber Group in WWII

Possibly a commemorative decal, not sure. Google is your freind.

 

Here is one just like it. I thought it was a racing decal but it must be something else.
