Have this beautiful picture received yesterday, well packed! Taken the pictures fast times from the box and placed on the page. Step 2 was the installation of the supplied image holder at the rear. Have this center the pictures attached. With the screwdriver small holes pre-drilled / turned! Brought screws by hand something in position and subsequently tightened. Step 3 was the idea with which distance I bring this on the wall .... I 1cm gap selected and then placed one by one on the wall. Adjusted by means of a small spirit level and everything was done ... just a beautiful eye-catcher so I mean look yourself .... Gladly again !! The optics has what, the workmanship is very good for the price !!
