Hi Cathy,
I would almost definitely say yes, the feel of the glass, the shine to the inside, all feel very modern. Ivo's date of 1960s onwards feels much more like than end 19th century.
I love the Pressglas site, but have real problems with it, as I speak no German (other than zweimal caffee bitte.... noch zmeimal caffee bitte.... danke...which few words get me a loooong way......) so can't work out what to search for. And to go through ALL the catalogues... phew!
