Boundary
No caption establishes real location or mining permission.
Complete source
Fictional two captions: version1 says “This rock came from here”; version2 says “The supplied drawing does not name a quarry.” Neither names an actual place.
Invitation
Choose a keep/change/open reason for a display reader.
Next try
Add a reviewed public source date if one is actually available; otherwise keep location open.
Ordinary possible response
I prefer the bounded second caption because it does not invent a local quarry.
