APELDOORN: TALENS & ZOON, 1925-28. A very scarce set of Dutch educational games made of cards sets, each series (A,B,C) possessing 20 coloured and 20 uncoloured cards with identical outlines. Series A & B include loose paper circles (in 3 sizes ) and loose paper squares ( in 1 size ) provided in glassine envelopes and all three sets include the printed instructions in Dutch. The images progress somewhat in complexity, with squares gradually playing more of a part, and the children playing with them are instructed to start with the coloured cards as example and then apply the coloured circles and squares to the uncoloured versions with glue. Different effects will be achieved with the use of different colours on the same object outline and this, of course, is part of the learning process. The series D is not included with this set; each series could be purchased separately. Sara Maria Bouman-van Tertholen (Rijnsburg 1878-Amsterdam 1950) was a Froebel teacher, author of books of art instruction for children and creator of songs for children. The concept of the game and the abstract forms of the individual card illustrations clearly fit into the rise of Modernism during the period of publication.
