From EarthTimes.org:

A German children’s book can be published in the United States after a publisher there dropped its demand for the genitals on a picture of a statue in it be air-brushed out, it was revealed Thursday. The German illustrator of the book had angrily complained of censorship and withdrew it from the US market last summer after being told that shoppers might object to the nudity.

[…]

The offending male organ is a tiny squiggle in the picture: the male statue itself is only 7.5 millimetres high on the page.

[Emphasis added]

All we can say is, whoever got upset about this in the first place is a bit of a tool.
