I've had this in my possession for years now. My grandfather owned a Shell Gas Station from the 50s to 70s. I never got the opportunity to meet him as he passed before I was born, but going through some things I found this tie clip again and I think it finally hit me that it could be a Shell Oil Co. item. Does anyone know anything about it? I found other Shell tie clips but none that looked like this so I'm not even sure it is actually from Shell. Any help and value would be greatly appreciated. Thanks in advance!
