Bandit Signs (Are they legal?)

[Clayton Coombs]

I see them everywhere but from my understanding they aren't legal. I am contemplating on having some made and putting them on street corners in areas I want to invest in. Does anyone have any experience with them? Are they legal? Will I get fined? I would put my google voice number on the signs which is forwarded to my cell phone and also thinking about putting my investment website where they could also contact me. I imagine each city will have their own rules, I'm wanting to put them in the West valley (Phoenix, Glendale, Avondale, Goodyear, Etc)

Suggestions would be helpful, I don't want to get fined. Thanks
