Courtney seems pretty unfazed by how old the pictures are, plot convenience, I suppose.
Looking at all the decisions she's made so far Courtney is pretty dumb all round. The Golden Age characters not ageing / ageing very slowly is straight out of the comics though, so I'm glad they kept it.
The one thing I wish they'd clarify is how publicly well known (or not) super-humans are on Earth-2. No one seems disbelieving of the existence of super powers but they don't seem to have heard of the JSA either.
