what does the logo with a crown inside a star mean?

On a few freeways, I noticed that every couple of feet, there are poles on the sides of the freeway with little logos of a crown inside a star. This was in Houston, Texas, so I thought that maybe the star was the Texas star, but what does the crown mean?

Were you in Sugar Land?

The crown in the Sugar Land, TX logo comes from the Imperial Sugar company logo.

Oooh. That makes sense. I see it all the time, and it just seemed so mysterious. hehe. It just looks so weird to see both the Texas star and Imperial Sugar logo together. I thought it was related to the origin of Texas or something.
