Edward Lear (1812-1888) is hard to beat for humor and pure imagination. I like him almost as much as Heinrich Hoffmann, the creator of the "Slovenly Peter" book (which came out in 1845). In 1846, the first edition of Lear's "A Book of Nonsense" (pictures and funny limericks) was published under the name of Derry Down Derry. That same year, Lear gave 10 drawing lessons to Queen Victoria. He travelled all over the world in his lifetime and he sketched and painted as he went along. What I am showing here is just the tip of the iceberg of Edward Lear's works. He also painted in a very naturalistic style, mostly landscapes and birds.
