A bunch of lambs run and play and jump off rocks in this charming, playful lambs drawing. Two ewes look on in this black and white sheep image that is copyright free and in the public domain.
I found a number of great images in Baby World Stories, Rhymes and Pictures for Little Folks compiled by Mary Mapes Dodge (1830-1905) and published by the Century Company of New York. The work bears a copyright date of 1884 and does not identify an illustrator.
This image is copyright free and in the public domain anywhere that extends copyrights 70 years after death or at least 120 years after publication when the original illustrator is unknown.
