Help identifying cartoonist?

So, I found an cartoon online that I want to use for a postcard reminder I want to mail this week. Unfortunately, I’m having a terrible time identifying the artist so that I can ask for permission.

I’ve been looking at the various websites that I’ve seen the cartoon posted on with no success, and have tried googling the signature but I don’t think I’m spelling it correctly.

Anyone want to help? This is the cartoon, but not the artist’s blog:

Meaning of life

Robert Gumpertz.

Boy, do I feel dumb! I kept spelling his name “Gumpres…”

Thank you so much!
