hello Cathy - wish I cud confirm for you, but regret that you are asking the wrong person.

I have no real knowledge Italian/Salviati pieces such as these - however, Ivo seems conviced that yours are Salviati, and bearing in mind the similarity, then perhaps mine stand a chance of a similar provenance - I'd like to think they were

(I have a single Salviati wine glass, and it is a delicate and attractive piece). However, I notice that neither Anita or jp mentioned Salviati when replying. It's not my area really -
plus the fact that I don't have any books devoted to Italian C20 glass. I wud have bought these cocktail glasses anyway to go into my drinking glass collection, but I do like your little 'thimbles' - surely you cud find some space for pieces so small

I bought an opalescent/gold bowl from this morning which I will post, and which may possibly be Salviati. :X:
