Maison Williame

Our firm, the country's longest-established in this field, was founded in 1925 by my maternal grandfather UEG Williame. After having the opportunity to work alongside him for a number of years, I carried on after his death, with help fr om my father Jean Kaiser, in running our establishment.

As stamp-lover, I’ve worked enthusiatically with Mr. Jean Baete, AIEP expert who is well known among specialists. It was with him that I learnt and perfected the  basics of our expertise. Acquisition of his standard-setting collections, combined with my grandfather's passion,enables me to draw up universally-appreciated  authenticity certificates for stamps and letters from Belgium and Congo.

After taking over the highly respected firm of Maurice Baeten in 1995, which specialised in Postal History, we continued to build on our great strengths, viz: postal history, rare stamps and large, high-quality collections, with the result that, for the last 10 years, we have had sales at our company's public auctions from most of the large collections in the country.

Discretion, meticulous description, a lavishly-illustrated colour catalogue, vendors paid within the month: these are some of the principles to which we adhere. The results achieved, that is to say the quality and size of the collections entrusted to us and the abundance  of record prices seen at all of our sales, do not therefore happen just by chance. 

Located as always on Rue du Midi right at the heart of Brussels, for over 80 years we've been the meeting-place for collectors from Belgium and around the world. Maison Williame is a family firm (for a little history, note our telephone number: 02 512 76 27 comprised just the 5 last digits in the day of my grand-father, i.e. 276 27), wh ere you will always receive a warm welcome  and get sound advice, whether it's for an opinion, expert's report, purchase or a sale.
