Peter Simon’s collection is large enough to read as a survey of modern and contemporary art, but its more useful story for collectors is personal: how a commercial eye trained on textiles, colour and pattern became an art-collecting instinct — and why conviction still matters when markets move against you.

Rana Begum treats light as a material. Her first New York solo exhibition offers collectors a precise lesson in how architecture, daylight, colour and movement can keep changing an artwork after it enters the home.

Joseph Yaeger’s Agita begins with images we think we recognise and a text we cannot fully trust. We examine how memory, found imagery, watercolour and material accident turn contemporary image culture into psychologically unstable painting.

MoMA’s new photography exhibition begins with Marianne Wex’s radical archive of gendered body language and expands the question through seven contemporary artists. The result is a sharp study of bodies, space, archives and who controls representation.

Alix Vernet sees the backs of New York air conditioners as archives: fragile aluminum surfaces that record weather, maintenance, touch and heat exchange. LANDMARKS turns overlooked infrastructure into some of the city’s strangest new monuments.

Paris Design Week is too large for a checklist. Our collector’s edit focuses on the places where collectible design, exceptional craft and historic interiors create the strongest opportunities for serious looking and collecting.
