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.

And we've got the ephemera-collecting niche of the seed/garden catalog.  They too contained gasp-inducing (I'm only speaking for myself) illustrations of fruit.  These are from 1936.

And Mastodon strawberries!

And then there are the floral illustrations in these catalogs and many of them are just mad.  Here the centerfold, sadly somewhat cropped by my scanner.
