After more than 40 years of work, a notary retired.

He just needed a series of personalised documents to complete his paperwork and communicate with all his contacts and connections.

The client was presented with a kind of test by suggesting an ironic hidden message which showed, after so many years of serious work, that a conventional pen was running out of ink.
