"11x14" house illustration done in pen,ink and brushes. 1980's

I've been drawing houses since 1978 for Realtors and private Home owners and have gotten very good at detailed line & brush work.
At one point in the 80's i was drawing 40 to 60 houses per week.
I'd work 18 hour days stopping to eat a pizza and go back to work ,and it was like a production line.
I learned to be really fast with the pen & brush, and it help me with my detail.
I credit my work today from what I've learned from drawing houses.

I'd like to pass this skill on to someone who would really take an interest in this style of work, and none of my family cares to put in the effort and learn, and because it takes years of devotion and love to master this skill .
