Here are two pictures I downloaded from my mother’s iDisk last night. (Ah, technology!) I was perplexed by the first one until I studied the second. It appears the figures are wax, and the pouring water may be some kind of resin. Or not. Decide for yourself: if you click on the pictures, they appear larger.
And let me point out that the man in (comparatively) modern dress is my father, looking very British himself.
