Adam's art glass pieces are individually made one-off's, many now commissioned by interior designers and architects
From the website you will see that his work is exhibited at many galleries in USA as well as UK. He also shows at the New York Sculpture Objects & Functional Art (SOFA) expositions http://www.sofaexpo.com/
as well as many comtemportary arts events in the UK.
I am more used to seeing Adam's more recent work which for which he uses more sophisticated and indeed adavnced techniques. Your interesting early piece, made less than 2 years after first setting up a studio, shows his early sensibility to classical form and proportion. Very elegant.
