Great, vintage creepy crawly drawing of a gnat larvae. This drawing looks a bit over-sized (even the actual size portion) but it is a great bug image that looks like a caterpillar. It was recovered from the 1851 work >Illustrated London Reading Book, 3rd. ed, a work published by The Illustrated London News.
