But the sales are not going badly.
The booklet is - very modern - printed according to the POD (printing on demand) system. In runs of about forty or so maximum.
And with that POD event, a software check has occurred, which means that a number of buyers have received a booklet with a few duplicate texts.
If you belong to that, or just want to dream about 'motorcycling 1.0', then you can email Dolf via firstname.lastname@example.org. He will then send you a set of fresh columns.
