In 1950, a bank of the Nederlandsche Handelsmaatschappij opened at 34 Blaak, founded in 1824 on the initiative of King Willem I to revive trade. The building was designed by the Rotterdam architects AA van Nieuwenhuyzen and Chris Elffers, who simultaneously worked on the design for the Rotterdam office of the Nationale Levensverzekeringsbank on Schiekade. The bank building, together with the adjacent bank buildings Blaak 28 and Blaak 40, is one of the first buildings to be built after the war. In 2010, the building was given the status of a national monument, but it has long ceased to be a bank building. There is a side entrance to the building in Posthoornstraat, which is adorned by two figures made by sculptor Hans Petri. On the left masonry pillar is a 'money carrier'. He wears a cape and has a coin in his left hand, a (money) bag in his right hand. The figure on the right is the 'keeper of the keys'. This figure also wears a cape, but also a large key on a chain. They both look down towards the entrance.
