Another design (below), the banner of the state arms (lozenges in the Grimaldi family colours, in heraldic terms "lozengyaragent andgules"), was used at various times, particularly in the 17th century, as an unofficial flag and still appears in some royal photographs.[clarification needed] However, it has no designated use and does not represent any Monegasque official in particular.
