Years ago, I saw this sign and couldn't make it out, which is what it is suppose to do. Make you think. Then I saw what it meant and had to make one. I don't think it is hard to read with my pictures, but it did confuse many people. Like they say, it is very similar to life..you can't seem to work things out and all of a sudden you realize what is missing..
Till next time, keep looking up.
