This is a vintage, children digital stamp of an illustration from the childhood nursery rhyme, Little Jack Horner. I found this cute nursery rhyme graphic in a child's primer book. I just love the black cat that is curiously looking at the plum that Jack has pulled out of the pie with his thumb.
This is the Mother Goose nursery ryhme:
Little Jack Horner
Sat in the corner,
Eating a Christmas pie;
He put in his thumb,
And pulled out a plum,
And said, "What a good boy am I!"
