Help me find some comic strips

[Jellby]

I have managed to get the complete set of U.S. Acres comic strips (aka Orson's Farm), by downloading at different times and with different qualities from:

http://www.gocomics.com/us-acres
http://garfield.com/us-acres

Except for the last three strips. After the last daily strip (1989-04-15), there were 4 Sunday strips. The first of them can easily be found online, because it fits the days' sequence (for example here), but I can't find the last 3 Sundays.

Apparently, now at least, in gocomics they just repeat all the strips in sequence from first to 4th-to-last, once and again. In garfield.com every 2 years it's the same strip.

Well, I have the strips, because some time ago they could be found in some of the above sites (I forgot which), they can also be seen here, but I don't have them in color, like all the others.

So, as a challenge to everyone here, can you find them with an acceptable quality?
