The flag is described as green and white. Ertslijn used essentially the same design with ERTS-LIJN. on the white stripe, including the dash and final point; the letter colour is not stated in Jansen & Van Heck. A 2006 auction example has italic company lettering and an unusual black border round the whole flag. Fischbachâs version adds B.V. before the name. Jan Mertens questions the bright green of some published renderings because photographed examples are darker, without fixing an exact shade.
