Hi John,
I would say, most definitely.
On my visit to Murano 2 months ago, I saw and handled statues like yours.
Some were made by Andrea Tagliapietra, whom I had the pleasure to watch working. I wanted to buy one, but it was a choice between one of these and a lovers knot; I chose the lovers knot.
I am pretty sure that others on Murano make these statues as I also saw labels saying Toso & Tagliapietra.
