Featured Glass Vase Identification/ signed HELP

A little background on this beautiful vase . I had admired it at my soon to be stepfathers home in Approx 1980 ish , he said it had been in his family for many years , belonged to his grandmother. One year he wrapped it and gave it to me for my birthday and said “ I believe if someone admires something so much , they should have it “ with that said I am finally able to display its beauty and of all the years I have looked at , never seen the initials / markings on the bottom…anyone have any ideas? It’s Approx 6.5 in tall . Thank you all very much …

 

Have you checked it with UV light to see how it reacts? I like it too, unusual.

 

What do the letters on the bottom look like to you?

 

You have excellent taste, but unfortunately that’s all I know.

 

I really like it too. That is all I got.

 

I found a set of goblets signed "ec" but they didnt know who either. I think this is from 1982 so father in laws story might be a hair off. Family histories often are. Its a lovely thing Id gladly display.

Okay my stepdad got back to me with info, I think sometimes his memory is better than mine Lol! He gave this to me in 1979 , his “grandparents “ traveled often to Europe … France in particular, and indeed passed it along to him . So myself being relatively new to antique knowledge, could the 82 be a model number of sorts? Or just part of how this particular artist signed his/ or her work ? It truly is driving me nuts Lol! Do appraisers have this kind of knowledge? Any hoots if ( when ) I get to the bottom of this , I will give y’all an update

 

Might it be EC62?

 

When I zoom, it looks like 62. The goblets look like 82.
Do you call this pulled feather? I saw a lot of it when I googled.
