From the archives of Swedish newspaper Aftonbladet:
The man on the left is delivering newspapers, the man on the right is the Aftonbladet photographer. Picture taken in 1964. And they say the Hasselblad is a studio camera...
Actually for my part my unicycle skills and the unicycle are a bit rusty and I would not try that at home or on vacation with a Hasselblad, RB or RZ67. I will leave that pratt falls for others with or without a camera. No not a Leica or a Rollei for this one.
