Mold Blown glass or not... ?

I found this set the other day at a thrift store and I really love it! I had heard of "mold blown" glass and thought I knew what that meant, but from further research I read that method was only used in the 17-1800's in Ireland and these look more 1960-70's to me...

They're marked "Made in Italy" on the bottom and the handle on the pitcher looks to have been put on after the pitcher was formed.

Anyone have any ideas?

Much appreciated!
