Harry Leat’s unusual trick ‘Grub’. A butterfly production from toast

This is a bizarre trick by any standard. It is reasonable to ask why a butterfly should be produced from two slices of toast. I will not begin to explain it, but urge readers to look at Leat’s own three page description which I have included with the illustrations. The advertisement reveals not only the play on words on which the humour depends, but also an insight into Leat’s sense of humour.
