This Lyra Rembrandt set might be from 1970s:
There are several modern sets that I also would like to get: Bruynzeel Design or Design Aquarel 48 set, Cretacolor Karmina or SoHo Urban Artist 72 set, Cretacolor Marino 36 set, Daler-Rowney Watercolour 36 set, Faber-Castell Art Grip Aquarell 60 set, Lyra Rembrandt Polycolor 72 set, Marco Raffine or Marco Renoir 72 or even 48 set, Staedtler 'nameless' or Luna 48 box, Talens Van Gogh Colour or Watercolour 60 set. New or slightly used as long as nothing's missing.
Like I wrote, I can give a Bruynzeel Expression 36 tin, a Stabilo Aquacolor 36 tin or a Maped 48 cardboard-box set (lower middle class), a Koh-i-noor Hardtmuth Polycolor 36 set in wrong Chinese tin (they came in a plastic wallet) or a Staedtler Karat 36 tin (upper middle class), a Faber-Castell Polychromos or Albrecht Dürer 36 ~ 48 ~ 60 tin with original or customized colour range, or almost any Derwent 72 tin.
Any interest to swapping?
