Chris Suma's collection at Antiques Emporium has a strong focus on glass from the Art Nouveau and Art Deco period. His expertise lies in the glass art of Johann Loetz Witwe, who is considered one of the leading names in the production of iridescent Jugendstil glass.

Antiques Emporium's specialised collection is distinctive in the Netherlands, which Chris Suma presents with a fresh vision. He offers his extensive glass collection, combined with other unique art objects from the period, to the public with passion and enthusiasm. Chris Suma regularly presents at art fairs in the Netherlands and Belgium, but his collection is also accessible worldwide, via his website. As a result, he has also built up an extensive international clientele. 

Chris Suma is also involved in researching the glass production of Johann Loetz Witwe in cooperation with the international research group Loetz. His passion for art is a great motivation for the many international trips that lead to the acquisition of these most unique objects and collections.

Antiques Emporium's collection is ever changing and diverse, yet regularly includes renowned artists such as Louis Majorelle, Émile Gallé, Daum, René Lalique, Charles Schneider, Fritz Heckert, Louis Comfort Tiffany, Riessner - Stellmacher & Kessel, etc, in its collection.
