The preface to the 1967 Jan van Krimpen “Tentoonstelling…” booklet for the exhibition at museums Meermanno and Plantin, thanks a professor W. Jackson MacWilliams in Puerto Rico. Someone who contributed materials to the exhibition. Anyone know prof McW? #janvankrimpen #puertorico #meermanno

Interesting new display of this old mechanical Gestetner duplicator machine at the Huis van het Boek museum in The Hague. I need to find out why it is there, I doubt the baron was into it. #meermanno #gestetner #duplicator
