How to determine the value of design

Design pieces especially furniture are mostly industrial design and so often pieces which are produced in higher numbers. We have to difference early pieces from later piecer or copies of an successful design. Other pieces like glass or objects in a lower number are signed or stamped.

What to look for when appraising design

Producer marks, stamps and the right material and little differences in the technical construction. Often the later pieces or remakes have little differences to simplify the production.

Is it a replica or an original

Look for papers or documents. When was is bought and is there a guarantee or some papers. Images of the technical details especially with design furniture could clarify if it is a later remake.
