Paul Thek’s sketchbooks and drawings fill vitrine after vitrine at the Modern Institute in Glasgow Photograph: Sheldan Collins

You could spend all day poring over these private works, with their landscape watercolours and pencil drawings, bits of bodies, Christ as an erect penis, pages and pages of poems, thoughts on art and religious sentiment Photograph: Sheldan Collins

After having been a leading, if not cult figure in American art in the 1960s and 70s, Thek died in 1988 Photograph: Sheldan Collins

His posthumous career is only now gaining ground Photograph: Sheldan Collins

On a makeshift platform in the Mackintosh Gallery at Glasgow School of Art, sculptures of Charles Rennie Mackintosh and Margaret MacDonald, made by Dutch artist Folkert de Jong, look down on the school’s plaster casts of Michelangelo’s slaves Photograph: Murdo MacLeod for the Guardian

De Jong’s figures often have weird coloured splats on their faces, like industrial war-paint, and their clothes are spattered with gouts and drools of quick-setting resin Photograph: Murdo MacLeod for the Guardian

The festive and the grim, the lively and the dead all have their place Photograph: Murdo MacLeod for the Guardian

Swags of cellophane festoon the ground floor hall, with its high windows, ornate ceiling and rows of Corinthian columns. This is lightness versus gravity, a foil to the pompous decoration of the building Photograph: Ruth Clark/Courtesy of Galerie Gisela Capitain, Cologne

Wolfgang Tillmans, at Common Guild, is captivating too Photograph: Ruth Clark

Tillman’s images take us from a colourful close up of a car’s headlight and trim to a portrait of an onion Photograph: Courtesy the artist and Maureen Paley, London
