Description of the flags

De Nederlandsche Stoomboor Maatschappij (Netherlands Steamboat Co) was the first steamboat co in the Netherlands. It was established with the help of King William I in 1822. In 1823 the first Dutch steam vessel was launched: a ferry on Hollands Diep named Wilhelmina, developed by G.M. Roentgen, the steam engine built in England. The company not only was involved in shipping but started to build vessels as well on its own shipyard. Services. First services were Rotterdam-Antwerp (1823-1847) en Rotterdam to Mannheim (until 1955). In 1886 the name of the company was changed in Nederlandsche Stoomboot Reederij. The original company had a wide range of house flags during the years.

The green in the fly of this design suggests it's an amalgamation with only in part a Rotterdam origin, with the green for Rotterdam.
