Veronica — Thanks for resurrecting this topic. I'm now convinced that they're not Walsh, but Venetian, from an early C20 range that inspired Walsh's iridescent glass. You can see low candlesticks in this or a very similar range in the above photograph, a pair in green left of centre and a pair in pink to the right. Behind the green candlesticks you will see two further examples — short-stemmed vases in pink and blue.
I showed similar pieces to Dr Rosa Barovier in Venice some years ago, and she confirmed it as Venetian, giving it a date of around 1895–1915. I'm unsure as to whether this was a launch or production date. The pink effect with flecks of deeper colour she described as "maccette", a term I've not found elsewhere. Dr Barovier also told me that it had been made by various glass houses on Murano so was now impossible to attribute to one with any confidence.
So, could Napoleone Martinuzzi have utilised this basic range or style, expanding it into new products with his naturalistic additions?
Fascinating.
