Thirty Years ago our Base Set A was the smallest set of blocks we made - the "Basic Set." With the advent of cheap imported plastic toys, however, we have long since introduced smaller sets which can be found among the Beginner Sets andf Small Sets. Ultimately, however, the Base Set (below) is probably the target toward which parents should work their way. There is no necessity for buying all your blocks at once. Kids play with a real blocks until they are 13. Our customers tend to come back for birthdays and holidays for some years.
