The distribution of pictures was very wide: "yea many tymes, blacksmithes, cobblers etts., will have some picture or other by their Forge and in their stalle. Such is the generall Notion, enclination and delight that these Countrie Native have to Painting" reported an English traveller in 1640. There were for virtually the first time many professional art dealers, several also significant artists, like Vermeer and his father, Jan van Goyen and Willem Kalf. Rembrandt's dealer Hendrick van Uylenburgh and his son Gerrit were among the most important. Landscapes were the easiest uncommissioned works to sell, and their painters were the "common footmen in the Army of Art" according to Samuel van Hoogstraten.
