i think it was limited to 2000 (maybe Jrgen pressed "9" instead of "0" by accident

)
I bought it on ebay indeed. Only paid 30 Euro's. I quite happy with that price! It was still mint and in original packaging.
Usually the final price is much higher, about 50 Euros.
I don't know why i got it that cheap, maybe i was just lucky 8).
Kleine ?ngste H?rbuch is still available in the Janus Shop.
I bought it there an it was number 580 of 666, so if you want one,
you should hurry, i think they might already be at ~620 or so.
