Two plain janes

Of course, one is more of a plain jane than the other. I love both for their simplicity in different ways. The clear vase is hallmarked [D][L], London, 1923, the red vase [D][L], London, 1925.
The red vase has regular humps arising at the base, reminiscent of the humps seen in Art Nouveau glass, but with a vibrant tango colour.
Any additional information or links, as ever, gratefully received.
I am linking into Art Deco, but glass produced around this time does straddle the two movements, as Alfredo wrote. Maybe these are more Nouveau than Deco.
