The obverse of the 20 złoty coin depicts a plan of the port of Gdynia. The plan in the form of a coloured photocopy from the collection of the Gdynia City Museum, made by Leon Wilbik on the basis of Tadeusz Wenda’s design, was used as a model. The plan was probably drawn up around 1936. It shows the status of the port in that year as well as the Industrial Canal (which was ultimately never built), some of the port warehouses as well as embankments and basins which were planned for construction in the subsequent years. The reverse shows the bust of Tadeusz Wenda reproduced from portrait photographs taken in 1918, which are deposited in the collection of the Gdynia City Museum. The fragments of the portal of the openwork gantry crane shown in the foreground were used in Wenda’s times and are still in use today. The cranes in the background are contemporary devices. At the port, the past blends with the present.
