Rotterdam in the Netherlands

From the Dutch city of Rotterdam: gateway to Europe. Rotated stamps and a machine postmark. They weren't put there to look pretty. A strip of three stamps from a set of six from a sheet of ten from 2012 featuring Dutch cattle breeds. From left to right are Witrik, Lakenvelder and Groningen White-headed. And the stamp on the right is a December holiday stamp from a sheet of ten from 2005. It makes more sense when you see the rest of the stamps in the sheet.
