Brain Cells on Parade

I frequently travel on both the #36 Broadway bus and the #22 Clark bus here in Chicago. As I journey up to my neighborhood on the north side, either route takes me past a large number of dry cleaners. There is one very small thing I’ve been meaning to bring up for a long time now. It has to do with these neon hangers that may be seen in the front windows of virtually every one of these establishments. I have quite a few questions about these neon hangers – when did this become the standard for how a dry cleaners front window should look? Is this how they do it in other cities? What lucky neon sign company holds the trademark on these? Are these a sign that the cleaners is controlled by the Neon Mob? Also, whereas some cleaners will have a mere 2 or 3 neon hangers on display, others will have a dozen or more running along two sides of the building. Does the number of hangers correlate to the quality of work done there?

I know that we all have more pressing matters to attend to, but these questions have been nagging at me for some time and I would appreciate any guidance you might have to offer.
