This is a very interesting collection of technical drawings all drawn by hand long before the age of computers.
This is the entire course work of one Fritz Schubeler Von Winterthur who attended the Eidgenossischen Polytechnic in Zurich and was awarded his diploma in 1901.
There are over 70 beautifully executed technical drawings in the portfolio which includes frizt’s diploma certificate.Its great to see how Fritz progressed during the course from simple drawings to highly involved creations.
The presicion is remarkable. Each picture is signed in the corner.
