The flag has alternating white and blue horizontal bands with an overall black M. Schneider’s description gives widths of 9:3:1:1:1:3:9. Nüsse’s table flag confirms that the outer blue bands are wider than the central white and blue bands, but Rosanoski finds its proportions different from that numerical sequence.
