from unexpected places - vintage astronomy prints

These are from Etsy's Antique Print Store.  What kind of characters
would own them?  What kind lived through some of these spectacles,
lives forever changed by wonder?  Are any of these characters yours?

Somewhere, something incredible is waiting to be known.
- Carl Sagan
