Great. Even greater than Toby. And really old. All the chimneys beneath one another. The tracks could all start on the left. The piling is a little bit difficult as well. The time lags are very variable. Otto says: “It is easier to keep something simple in mind than to forget something perfect.” That is sometimes right. Sometimes not. Mostly, I like number and picture combined the most.
