Sign maker here...it's tough to tell from the photos but there could be several reasons. Assuming it's a 4x8 it could be the cost of the frame, which looks like it could be extruded aluminum. Or it could be the rental cost for a month or several months, if it is considered a billboard. If it is not a rental and just a one time purchase, it may be a sublimation print on fabric, and that can get costly. If it's just cut vinyl on an aluminum panel, then it's way way over priced unless you include the frame cost.

I'm almost positive the cost is for billboard rental, especially since you can see it's set on concrete footers.
