Mural paintings.

At Alto de Abraveses Avenue, Viseu.
This was painted on walls of the National Guard headquarter. An officer noticed I had my camera ready to shoot across the fence and came to tell me I was not allowed to photograph the buildings and the fleet of vehicles of that military headquarter. I told I was only interested in the mural paintings, making zoom to catch them better, thus avoiding the buildings and the vehicles. The officer understood I meant what I said and kindly allowed me to take the photos of the murals - a gentlemen's agreement.
