Jell-O ice cream dessert suggestions from 1925.  Ice cream was often prepared in loaf form to be cut into slices for serving.  Usually I like old-timey ways of things but I'd really prefer my ice cream be roughly spherical.

Very nice rendering of the Jell-O with the bananas in it, I feel.

I'm not sure what Jell-O sponge might taste like, but the copy says it's the 'aristocrat' among gelatin desserts so it must be mighty fancy.   And the beautiful bowl and berries, very nice.
