[amsat-bb] Garrison Keillor's callsign?

On his last radio show, during his Lake Woebegon segment, Garrison made reference to his early days in radio when for fun they used Morse Code...

So the question becomes, who has a QSL card from Garisson Keillor?

He is not currently in QRZ.com but if he was like many of my friends back in the 60's, they did not renew heir licenses...

So, who has a paper callbook say from 1956 to 66 and can look him up?
