If you would like to have a book signed, please send it to this address as well and don't forget the stamped self-addressed envelope (preferably air-cushioned). The postage costs in Gernmany are according to the post office:
Book shipment (Germany): 1.00 euro

Letters (postal items) should also be sent to the above address.
If you want to send me an e-mail, of course you can do this as well.
However, I prefer handwritten letters. :-)
