I found this advertisement of a repro-company in the 1952 Christmas issue of the Dutch Federation of Printers. They proudly announce the purchase of a second Vandercook proof press. The quote at the top of the advert is from an article that appeared earlier in a publication of the Amsterdam Typefoundry. In the article, the progress made in printing and pre-press, is explained by a team of Dutch specialists who visited the USA. Printers in the Netherlands suffered of course from the post-WW II shortages and were keen to invest and to get printing again.
