Mostly designed by Edward Robbins, a scientific glassmaker who later emigrated to Canada and continued to create lampwork figures in a Mall.

All of the figures are shown in the Glass Zoo and mostly with multiple views and examples of actual figures. On request, I will add colour examples here but otherwise just use the catalogue images here.
