I would sure like to see it continue. I usually buy 20 or more and give out to many people associated with the auto industry. Everyone who I give a calendar to loves them. Think about how unique these are!
There is one hanging in the Chrysler materials group in Auburn Hills. One in the Mopar group. The Chrysler design studio person brought it home to her husband. Ford Design studio guys have two, and I ran out or there would have been three. GM design person gives it to her father-in-law who loves it. Guys who manufacture metallic pigments for paints and coatings love them. There's even one hanging in the Whirlpool color lab! The ladies there loved it too. Many more hanging about in industry.
I'm not sure about the sub-categories. I'm not sure I would get the same reaction with interior pics, engine pics, etc. But Dave & Judy have always asked for interior, engine compartment, and other pics for fillers. They could use project pics there as well. Just my opinion.
