CIRCLE TEMPLATE
Who would have thought that, after using my circle template at the American Fluor-office in 1966 for a.o. Aramco, it would be used again for my New-Year-cards 2018 (the angels halo)? We didnot use computers yet in the sixties for the technical drawings; it was all 'handmade' in ink and pencil. In the 80-ies we started working with CAD/CAM in different layers.
