Marketplace is a story about a place and people who value buy-sell, earn-loose options. A good deal helps them to live through another day. Not many of them take care of oil prices and skin color of the president of the USA, but they all run their „big business”. If you have just sold your axe, you may afford to buy a canary bird. If you sold two canaries, you would be able to buy a dog.
Traditional marketplaces are still visible in Polish cities. I used to visit one of them quite regularly where I could buy fresh fruit and vegetables. Sometimes I bought an interesting comics book published long time ago. If I had been lucky, I would come back home with a new photo portrait taken.
