A book found on the street proves a little inspiring; love the ladders, not sure of that bicycle in Amsterdam - could be a little wide for the 'fietspad'.
My favourite goes to the coffee pot; 'CafetiƩre pour masochiste' you can say that again, that's juts plain evil!
Isn't Amsterdam just great for finding things of pleasure on the street; one mans rubbish is anothers gem!
