What date did the “It’s a baby woman!” strip run?
If the first reult on this Google page is to be believed, it looks like it might have been December 13, 1973.
Unfortunately, you can’t view the actual book in Google books, and i couldn’t find a date for it anywhere else, including in a JSTOR article search and ProQuest historical newspaper search.
I subscribe the Newspaper Archive (wonderful site, btw), and mhendo’s site is correct…the strip appeared in newspapers on 12-13-73.
