The set is Dutch-styled in design. It was a promotional set for the brand chocolate drink brand Chocomel. It is a limited edition that sold mostly in Germany, Belgium and The Netherlands. The building has a crane mechanism like you can see in Amsterdam. Rebuilt with original parts and some random early Lego parts (they must have been using them up at the time) now hard to get hold of now pieces were used in the set. Early 70s Mini-figure legs on the barrow, mini-figure heads on the plant pots and the black cowboy hat. No box or instructions. See images, sold as seen. reach out if there are any questions. A lovely and quite an exclusive set that is over 45 years old.
