If you stay longer period of time in the Netherlands you become familiar with Dutch customs. One of them is using flags.
The picture is from the historical flags of Weesp (top) and Muiden (below) that have been esteblished at july 13th 1595 by the independent States of Holland and West Vriesland. These flags are at the doctors office in Weesp at the corner of Papelaan and Waarschapsstraat in Weesp.
As you can see these flags are very old and in use even today. If you would like to use this flag… feel free tot do so. You can buy one at your doctors office!
