Here is a small portion of the fantastic work by Marco Hitschler.
"Dear Sketchnote Army.
Last days I have created this large visual library, which I want to share with you. The drawings are taken from my reality, cartoons and drawing books. In general I have learned 2 things. First, you need not so much symbols to create sketchnotes. Second, some images get their association with the context around and not with the drawing itself.
Move forward, Sketchnote Army.
Please, do not miss the whole Visual Library on Marco's website!
Truly outstanding work, Marco!
