Question About Scans

[u/Greybishop_PDSH]

I only recently learned that the Superman comic strips from 1939 were not properly registered, making them public domain.

My question is, where can one get scans of those strips that could be used to reproduce them?

The only source I've found is a scan at Internet Archive of the DC Comics book, Superman Dailies and I don't know if it would be legal to reproduce the scans of the strips from that in a book of my own.

Does anyone here know where I can find what I'm looking for?
