Allen Ginsberg - the poem America

I've been working on this silkscreen for about 6 months. It is based on the poem America and I like the final result. It is 22" x 30" on Arches 88 paper. This is one of three variations of this piece.

The top image is America (Blue), the middle is Untitled, and the last piece (not shown) is America (Red). It's not easy to color correct these pieces, but I'm working on the digital repro so it's more accurate.

I have been invited to the Florence Biennale for 2011. It is an honor, of course, but very expensive to participate. Any sponsors out there? Any advice out there?
