Auction houses, Hungarian spas and being a flâneuse

As we step out into the April sunshine, we plunge into the thermal waters of a Hungarian spa, explore the history of the tulip and meet Venezuelan artist Sol Calero. Plus: we muse about collecting with Diandra Donecker, the woman behind Grisebach auction house in Berlin, and discover the joys of flânerie.See omnystudio.com/listener for privacy information.
