What is a "Rosa draling"?

[Don Rosa]

> The cover of the new Rosa story contains a coded message:

Yes, it was a secret little contest I did for the fans. So far I've had 26
people write in to me.

> On the last line, you can read about a "Rosa draling."  What's that? :-)

That's where I left a dot out of the cipher, so the 'w' became an 'l'.

> BTW, are Disney allowed allowed to sign covers like this?

Disney doesn't care -- that's a myth. It's certain publishers that don't
like it. But they put my autograph on the covers anyway, right?
