Camping on Öland

My grandmother is writing a book (she is 86) and I am helping her with the illustrations. Its fun working with her and it lets me try out new styles. We did one book last year where I did all the illustrations in pencil and this year im trying out black & white ink illustrations with crosshatch shading.

This is part of an image showing a camping trip to Öland (https://en.wikipedia.org/wiki/Öland) sometime in the 1950s.
