I illustrated the poem, A Baby Sardine by Spike Milligan. I envisage this illustration could be used as a poster in the context of a school classroom.

A Baby Sardine by Spike Milligan

A baby sardine saw her first submarine:
She was scared and watched through a peephole.
"Oh, come, come, come," Said the sardine's mum
"It's only a tin full of people."
