Stamp museum cartoon

The cartoon shown above appeared in yesterday's Los Angeles Times.

In case you're having trouble reading it, it starts off with the one young boy saying, "I wish summer vacation lasted forever."

In the next panel, he says "Instead of just seeming that way," to which his pal says, "Is your Dad really taking you on a tour of stamp collecting museums?"

Quite frankly I don't get it.

I sense the cartoonist, Jef Mallet is making fun of stamp collecting and/or stamp museums but again I could be wrong. I have e-mailed him letting him know I didn't find the humor in the cartoon.

His address (which is shown at the bottom of the first panel) is jefmallett@yahoo.com.
