Hi Ray,
My first impression is that there is far too much information on these and the logos are too intricate. Keep in mind that a 3-foot banner in a display window is awfully tiny especially if you are trying to catch the attention of cars passing by. You just want to catch their attention and get them interested to learn more. All that extra information is important, but could be incorporated into a smaller handout or sign for those closer to read. Maybe call it the "Home of Waukesh County S Scale Model Railroad" and put the rest on a smaller sign.
I knew a guy who painted billboards and banners. Some were on the sides of buildings and were 40 feet long or more. He always used simple words and large type and from a distance even those looked pretty small.
My 2 cents
