This illustration, required for a pamphlet, was performed starting from filter original blueprints; the cutaway perspective drawing was colored in acrylics on illustration board with an airbrush; retouchings were made in pastels and gouache.

A typical technical illustration, it is a fine, warm image with even the purpose of describing the interior of this object in detail, so it may be used for didactic purposes as well as for advertising.

Original request: "...Handmade, please; everyone has computer graphics today..." may sound amazing; we were in late 1993, and this was one of the last glorious airbrush illustration...
