The Moll de la Fusta was intended to become the first space for leisure and gastronomy in the city, a new place whose main axis was to form five chiringuitos of design that ordered to build the City Hall. One of these chiringuitos was occupied by the Restaurant Gambrinus, property of the businessman and architect Aldred Arribas, intimate friend of Mariscal. Arribas asked Mariscal for a decorative element that differentiated his restaurant from the other chiringuitos.

Mariscal designed a huge Gamba sculpture with lobster legs, inspired by the comic world. In 1989 he designed “Coby” the mascot of the Olympic Games in Barcelona.

When the Olympics ended, the area entered a slow decline and many bars and restaurants in the area had to close, including Gambrinus, whose Gamba emblem was kept in a warehouse. The Mariscal's Prawn was bought and rehabilitated by the Barcelona City Council in 2004, becoming a popular symbol of Moll de la Fusta.
