Oh and Uno. My first brother and I would gang up on the youngest brother giving him all the skip turns and draw cards. This was not very nice but at the time was very amusing.
The latter was architectural, with plastic model building elements held together by their vertical edges having grooves that engaged thin, stiff, steel wires planted vertically in the appropriate ones of a matrix of holes in a rigid plastic base-board.
I was too old for Lego by the time it appeared; but a friend tells me he uses Lego bricks to make temporary jigs to help assembling buildings for model railway layouts. They are moulded to a sufficiently high standard of accuracy and precision for him to trust the jigs to be square in all 3 dimensions.
Though not toys, my favourite books were A.A. Milne's Winnie The Pooh, (the bear who claimed he had "very little brain" had no waistcoat, either!) and a compendium, The Junior Weekend Book. Still have them somewhere, for sentimental reasons, because they were rather special gifts; one from a particularly inspiring Infants' School teacher who encouraged my appreciation of, and love for, the English language.
