Favourite Painters - Josep Tapiró Baró
Wow. Look at this! It's a WATERCOLOUR!! I'm just in awe... I might have to do a master study to try to figure out how he did it. This guy was born in 1836 so he would have used something called 'bodycolour' to do this too, which is similar to gouache today. But imagine the patience to do this! Just astounding. 

Google his name and you will see more of these beauties!
