In this vintage QSL from Swiss station HB9AAG, the operator appears to be making a plea for harmony. If an Indian, Cowboy, Eskimo, Asian, African and Marilyn Monroe can all get along, then we should be able to do the same, right?

I find the hope for unity just as poignant today as back in 1962. And notice too that HB9AAG apparently operated either QRP or QRO … 25 watts when conditions were good, and a pileup-busting 35 watts when he really wanted to heat up the ether.
The world needs more optimists like HB9AAG.
