Not sure on the statue but the islar maps norm like 3 to 5 mill and can sometimes fetch as much as 10 mil per depends on how bad the buyer wants them.
Personaly I'm looking for a lev 2 expertly drawn, and a lev 4 cleverly drawn maps to complete a set and would glady pay 10 per to get um. But they would have to be on catskills I wouldnt be willing to xfer for them.
