#47 - I like the simplicity of this, maybe just use three squares rather than for and we would need the font bolded some and Bank & Trust larger.
#50 - I like the swooshes, maybe use three and again, Bank & Trust needs to be larger
#49 is a bit too abstract although I like the simplicity of it.
# 48 emphasizes "Wood" which is not what we want to emphasize. Rather "& Trust"
