ID Drinking Glasses Please  

I just bought 2 sets of these glasses, each set containing 6 glasses. There is no mark on them but they came from an estate of a lady who owned lots of modern 50's/60's items, including Scandinavian. The feel and design both seem high quality to me but I don't know for sure if they are Swedish mid century modern or something more contemporary like Ikea or Crate and Barrel, although I'm inclined to think they are authentic Scandinavian from 50's/60's. Does anyone recognize the design? Top one is 4" high and the bottom 3.5".
Thanks!
