Help identifying this glass maker mark.

Hello!  I have a cased glass vase (purple and blue) with a "signature" on the bottom but I can not figure out the maker!  I have attached several photos.  I don't know if the signature is right side up or upside down!  Thanks for any advice!   photos

Two things that may help: 

1. Rub flour or finely ground coffee into the mark to get it to stand out more. 

2. Include a picture of the whole piece with something that gives it scale, like a coke can or a magazine.
