    §  483.  Signs  advertising  services  as attorney at law. It shall be
  unlawful for any person to maintain on real property  or  to  permit  or
  allow  any  other  person  to  maintain, on such property a sign, in any
  language, to the effect that an attorney-at-law or  legal  services  are
  available  therein  unless  the  full name of the attorney-at-law or the
