This will cost you at least 100 € via internet from second hand bookstores.
Many years out of print. But the legend – at least with some people – lives on.
I think it's obvious why nobody starts a new edition. It would be legally inflicted with charges concerning pedophelia, nowadays.
I too have no copy and never had. My infomation is also second hand.
There have been times in Western Germany when the book was praised for liberation, for a new understanding of sexuality as a part of lives of all people, including prepubescent children of both sexes.
You can see how times change when you look at Daniel Cohn-Bendit, a veteran politican of German Greens Party and member of the European Parliament. A very rhetoric guy. Mixed French, German and Jew, redhaired. Once he stood for the student rebellion movement of 1968. Later he was accused in German media for being an fan of pedophilia.
Once – and in fact quite a long time – there has been a famous magazine für younger people in West Germany, the in-crowd, the hipsters of that day, the liberated students, the protest generation, called: TWEN.
It always had a more or less bare chested girl on its cover.
Losing their blouses with the passing of the sixties. Magazine was filled with more or less intelligent journalism about „young“ culture. Jazz, Pop, Blues, they also sold records, Brigitte Bardot, Twiggy, nude Danish women, books by Updike, Mailer, Baldwin and Gore Vidal, Interviews with Che – or at least Dany Cohn-Bendit, Rainer Langhans and Rudi Dutschke. If you remember the name: Joachim Ernst Berendt, he made you familiar with Mingus. Willy Brandt was the hippest politician. State of the art graphics and design. Layouts by Willy Fleckhaus, who also designed Suhrkamp literary high-brow publishing house. Or Heinz Edelmann, who also designed Beatles cartoons in „Yellow Submarine“.
In fact it was read by teachers, civil servants and uncool clerks who never got the teenager girls they deserved. Let us taste a bit of wild, wild Germany we couldn't see if we left our houses.
All along the way they had a very clever American photographer, Will McBride, living in West Berlin. His b&w photography set the pace. He did everything, Adenauer, Romy Schneider, motorcycles. But as soon as he could get in close contact with really young and swinging people he felt like a genius and showed it. It seems he really believed in this generation - which no longer was his own. He was married and had some kids, boys. It seems years passed and he didn't notice that he had this special thing with young boys. Though his pictures showed it. These boys got younger by the passing years, starting around 25 and reaching 14 in the end. As an old men he lived a certain time with a mentally unstable end-teenager. He also photographed his own sons naked while they were teenagers. It was cool in those days.
Once he came across old German photos of people in cardboard boxes and stole the idea for Twen. Like every artist he stole all the time. He had success. Then the idea was born to do a book for familys with kids showing sex as a nice, human way of leisure und community. And by the way leading children into the know of some seldom bepoken facts of everyday life. („ein Aufklärungsbuch“)
This resulted in the book „Zeig mal“ (Show me) (it features in deed little boys of under 10 showing their penis to one another, as in reality once may have been the case). And it features a lot paper boxes with naked bodies of more or less beautiful people in them. Posing as families and all kinds of relatives including gay uncles and lesbian aunties.
You see, it was flower power and love every day of your life. It was welcomed at the day. The later parts of McBride's career didn't feature in German mass media anymore. The living with gay teenagers doing drugs and dressing in drag. But there are a lot books out now about his work.
In the meantime, him being dead, died at a high age, his name ist paired with the word BOYS, which might get to be his niche in art history. (But not in the sense of 8 and 11 years old, which might be your impression after „Zeig mal!“) Well, anyway, the more conservative and right-wing Germany of these days has chosen to have forgotten him. No one needs these books anymore.
We're already enlighted and our children are safe and sane.
