It's hard to tell from the pic, but the section with the model name is actually removable. it is on hooks and can be flipped over to say OPEN. It was a necessary part of the sign, otherwise regulations says they can put a 12x18 Model Open stake sign next to the large sign, which looks lame. So this is part of why the layout is done the way it is. The original idea had what was 2 4'x4' signs in a V, but not allowed by the city, so after a few go-arounds we got to this one. I do like the blue frame, but 3 of the 4 chiefs had specified they wanted white posts. You say you didn't use so many colors, but you actually did, lol. just different colors. As I said at the start, was on a budget, so... Anyways, I like your layout, and I wish I had the power to reject bad ideas from paying clients, lol. As for the framework, they originally wanted those plastic post covers, which are pricey, combined with what to do top and bottom to match. We used 1/8" acm for this job to keep costs down. As I said before, budget.
