Forty tradies and machines to colour, from the carpenter and the sparky to the crane and the cement mixer. The 32 tradespeople cover a whole building site. You'll find the usual crew (plumber, bricklayer, painter, roofer) alongside jobs that hardly ever turn up in kids' books: a glazier with suction cups, a steel fixer, a surveyor, a lift installer and a waterproofer. The 8 machines are a digger, mobile crane, cement mixer, dump truck, forklift, scissor lift, delivery truck and rubbish truck. Each picture sits on its own page with a blank back, so markers won't spoil the next drawing. The outlines are clear, with more detail than a toddler book. Ages 5 to 8 is about right. The crew comes from Idle Tradie Tycoon, the building game we're making at Schottlerworks. There's a note for grown-ups at the front with a QR code to the game. 84 pages, 8.5 x 11 in: 40 pictures with blank backs, plus a few pages up front.
