re: Other than if you are an attractive woman....

It’s because real estate agents are among the least creative marketers of any field out there. herd mentality is a big reason too. They saw their competition do it, who happens to be the hot blond, so the dude copies her. Again, because they are the most unimaginative, least creative group of people in the world. For 99% of the agents that exist, it was their failsafe job. Sally homemaker stays at home with the kids for 15 years, gets bored and decides she wants to go back to work. Sally, being an unqualified to do anything else, except not give blowjobs for the last 15 years, decides she’s going to sell real estate. Sally, being really excited about new career, needs to get her name out there. So she buys her new signs. And puts her face on it. And next thing you know, you’re driving down the street and see some ugly guys face on a bunch of frickin signs. That’s why.
