Architecture and Computer Graphics - using the initials "TMB" on my drawings, starting 1998. My business cards said "TMB Architecture/Computer Graphics". This changed, after 2004, when I became aware of a California law, stating that the Architectural licensed professional's name must appear in the company name. Missouri, though, has no broad definition of Engineering.

Colored original copies of traced house renderings, dated 1994;  with color pencil, dated 1998.

Colored thesis hand Architectural sketches, completed on paper in 1990.  The color pencil definition was added in 1998.  Color printing was becoming better known.
