Drop cap letter S decorated with swirling doodles. This letter image is quite different from the block-cut style drop caps we normally see. Seems like it would be good to use this letter S image for sewing as well as paper crafts.
I found several similar fancy letters images, drawn by Gordon Browne (1858-1932) in National Rhymes of the Nursery.
