The Eagles Lithographs?

I was curious if anyone knows where to go to sell some really cool original lithographs of the eagles album cover. These are a series of 5 and only 100 were made. These are also signed by the artist Boyd Elder. This comes from the series "American " and contain such work as Geronimo and One of These Nights to name a couple. The work was done in 1980. Any leads would be great!
