The end date for The Captain and the Kids, as cited in my book and elsewhere, is believed to be April 15 1979. The source for that is the distributor itself, United Feature Syndicate. While that may seem to be about as authoritative as you can get, I have found errors in their records before.
I just got an email from a Captain and the Kids fan who owns a piece of original art that seems to defy the UFS records. Here it is:
In case you can’t read the date, it is May 13 1979, a month later than the supposed end date.
There is a possibility that UFS cancelled The Captain and the Kids while there was still art waiting in the pipeline. That can happen especially with cartoonists who work far ahead of deadline. I have no idea, though, if John Dirks was one of those people.
The other explanation, obviously, is that UFS has the end date wrong in their records. Unfortunately my own collection and online sources do not shed any light. The latest printed strip I or the owner of this art can find is this episode from March 3 1979:
So can you shed any light on the mystery of the Captain and the Kids end date? Do you have tearsheets in your own collection that go past April 15 1979, or have you found an online source for later episodes? If so, please do let us know!
