According to a letter from H. Colijn dated February 22 [1921] (GAK/AK), Colijn had approached the publisher J.H. Kok at the request of the chairman of the Anti-Revolutionary Electoral Association in Hoek van Holland about publishing a cheap edition of 1921.01. If an inexpensive trade edition would not be possible, then Colijn wanted to receive a proposal from the publisher about what it would take to produce such a cheap edition.
