If I remember correctly, the earliest screenshots of Link's Awakening were in an issue of NP from the very end of '92, possibly even January 1993's issue. You would need to find scans of issues starting from Jan. 1993 and go back a few issues to find them.

EDIT: And the October clue probably means you could also start at Oct. '92's issue and go forward also. Okay, my info hasn't been terribly helpful, and I know of no place to find NP scans.
