A 10 minute walk South from Plaza Del Sol. It is a free museum dedicated to The history of Printing and Graphic Arts. On the first floor, there are several printing presses going back the when making books relied on strong men working huge vise machines, to mechanical beasts that cranked out hundreds of color images for magazines without an ink jet printer.
Also you will find the science and mechanics of creating the type settings that created letters as well as words. Getting images on paper before took a great deal of ingenuity and creating multi-color images took even more. Finding out how humans did it mechanically is a fascinating process you will find out here.
On the second floor you will find temporary exhibits dedicated to comic books, cartoons, and current animation. The history of the progression from paper comics to the modern movies is explained and is very interesting.
The museum is free and open Tuesday to Friday 10am to 2pm and Saturday 10am to 2pm. If you are into mechanical devices and fascinated on how things work, this is for you. A non Spanish treat you were not expecting to find in Madrid.
