Confused by an auction

Just saw this auction on mycomicshop and its got me confused.

[Flashback Lot of 6](https://www.mycomicshop.com/search?ItemID=58923181)

It shows a bunch of golden age books but the descriptions list dates in the 40s and the 70s. So I cant tell if these are golden age or reprints.

​

I remember having the treasury edition of the first All Flash Comics in the 70s but this isnt one of those.
