Glass cups what are they? Signature at the bottom can't figure it out.

Newer safety glasses. When broken shatter into a gadzillion million pieces.

To read the signature - Look down into the glass. That's the way many European import companies sign their glass.

 

Pasabahçe (the "s" should have a little tail too, but I cannot find the ALT code for it)

I have some glasses by them around here somewhere.

I used an online photo editing site to create a mirror image of the pic on your tumblers. I don't recognize the maker, but it might help someone figure it out

 

Typed what I saw into Google and found their website. Pasabahce Glass. Examples of their marks match.

Whoops I see someone else found it while I was working on it

 

BTW, if you list these, a better keyword then "cup" is "tumbler". Cups generally have handles, and are usually shorter. Tumbler is the term for drink ware with a flat base, like yours.
