This one was a different process–I drew it really dark, then I went to Kinkos and printed it even darker with the contrast turned up.
Then, I took Xylene (a solvent) and rubbed it on the back of the printoff so that it absorbed into the other paper. The images are a montage of pictures–the pavilion was built as an international expo in Barcelona, and it was right before the king lost his power: hence the broken king in the pool. The black poster pictures are original posters from the expo that I found online. I used the same process with the Xylene to transfer the picture onto the page.
