Probably a little dated now, but just in case. I have a nice antique print of Emeric's entitled The House at the Foot of Corcovado, that was based on a watercolour he produced in 1817 when in Rio de Janeiro. There is an interesting letter on the back plate from the donor of the item who was living in Rio in 1961. The images of the picture and the letter are viewable on my eBay listing - just do a search on the item # which is 320806553521
