Jan Kruis' Economical Impact

While making illustrations for Shell, he made cartoon postcards, which were used internationally. He also created a calendar and did many naturalistic paintings with mechanics like, tractors, trucks etc. as subject.

Many books have been published yearly of Jack, Jacky & the Juniors and are sold by the millions. Several of the books were translated in German, English and Swedish.

Due to this big success, many products were sold inspired by Jack, Jacky & the Juniors. Calendars, cards, clothes, kitchen-ware, bath products, post stamps etc. are available.
