Studio Glass Bowl Signed M Ihtr Tubos? Pink Swirls please help id

This is a studio glass bowl which is signed but the signature is hard to read - starts with an M and then what looks like ithr? and then the next word starts with a T and looks a bit like Tubos?  Can anyone please help me Id this?

Nice piece but sadly I don't know, you could also try another forum, IMO, they're better at identifying glass. Good luck and don't forget to let this forum know if they do get you an ID.
