Visitors of the threshold of Hans Hartman’s studio on the first floor of the Hoornbrekerstraat are called to a halt for a moment. A warm welcome by Hans invites the first curious person to take some steps forward, meanwhile the rear of the group is catching a glimpse of his impressive domain. Bright colours and substances of wet and dry paint on walls, ceiling, paper, pallet and the floor even on his painting clothes. The overpowering sight the amount of painted compositions commands everyone’s respect. On the easel the next piece on paper or canvas, usually "28 x 39 inches" parades. The industrious painter however always takes time for a new admirer, who in return has to immortalize that moment with a short entry in his guestbook.
