Dynastor napoleon

I've always liked Brassolids and this is the one I always wanted most. It's apparently very hard to get, and the only two I've seen for sale are these. The upper one, which I paid quite a bit for, is greasy but the underside is fine. I bought it thinking I'd never find another one, but the lower one was offered recently for a mere $20.00 with the condition that the left hindwing was stained. It is, but to me it doesn't show much.

Both are males as far as I know.
