Except a few rare series in 8 or 12 copies, most of the works are unique pieces. If you would like a copy in a different color than the one offered, please do not hesitate to request it. If you are interested in a copy that has already been sold, it can be produced again, but in a slightly different shade. Some works may be temporarily unavailable for sale because they are exhibited in museums for example. Make an inquiry to find out when they will be available!
