A little bunny looks like he just found some tasty new flowers to chew on. This vintage black and white image looks as if it could have been rubber stamped and may just end your search for rabbit images. It was drawn by Walter Crane (1845-1915) and included in The Merrie Heart A Collection of Favourite Nursery Rhymes. It dates back to around 1875.
