Dansk Møbelkunst, with showrooms in Copenhagen and Paris, deal in major examples of Danish furniture and decorative arts, of the highest quality and specifically from the period from 1920 through to 1970.
They have produced a number of outstanding publications on Danish furniture design and monographs on a number of Danish designers including Jacobsen, Klint, Kjærholm and Wegner.
Their web site is a good source of information where they profile pieces of furniture that are currently in their show rooms but their blog also includes assessments of important historic buildings in Denmark where they are associated with major designers from the 20th century or have important schemes of decoration.
People who deal professionally with furniture or ceramics or glass build up a considerable expertise in part because they are actually handling and examining and assessing an amazing number of items. More and more, this expertise is published by them on web sites and blogs and can provide important and interesting insights for the general reader. There is now so much material out there, available on the web, that occasionally pointers or suggestions might be useful.
1934 are an English company who also deal in 20th century furniture. They have an accessible style of writing on their site and have good photographs of pieces that have not been scrubbed clean and lost their patina … the pieces they sell may seem more realistic if your budget does not stretch to museum quality works. They also write general pieces about the period … for instance a good article on the Frankfurt Kitchen.
OEN imports into England and sells mainly Japanese ceramics and wood wares but also a selection of books and some glassware and some metalwork. Looking through the site reveals just how close Danish and Japanese design can be, in terms of aesthetics and in the way natural materials are appreciated and their characteristics and qualities exploited with such care by real craftsmen makers. The photographs, particularly the high-quality photographs of details of the works themselves, and the growing number of videos on the site of makers working are particularly informative and revealing.
