After seeing Wote's colouring book on the blog Arto sent me this great bloglet:
Hi Paul, here's my favourite colouring book from Finland. In the beginning of the Sixties, a Dutch printing company Mulder produced a small run of children's books for the Finnish market. I believe they were printed jointly for several countries, so this Askartelukirja (Activity Book) may well be familiar also elsewhere. Apart from one colour-it-yourself rocket, there are virtually no space-themed illustrations inside. But for me the upbeat cover makes up for everything, with two young astronauts sending off a rocket (to the SWORD Moonbase, no doubt).
The book has no year of publication (which is around 1964), but bears a product number 2812 C and "Printed in Holland". I have not come across another copy, neither used nor unused as this one is. As Wotan noted, vintage examples of colouring / activity books are scarce, an unused one even more so.
