Sure, you could spend years actually developing a reputation for trustworthiness and plain-spoken honesty, or you could just Photoshop your head onto the body of somebody who's already done that.
This lawyer in the Philadelphia area has chosen the more direct route.
I don't think there are any ethical problems with this advertisement, assuming it doesn't mislead people by falsely implying that the lawyer specializes in a particular area, like maybe rail-splitting or suspending the writ of habeas corpus. Otherwise, it may be tacky, but there's no First Amendment exception for tacky.
