Louis Poulsen, Light Years Ahead: The Story of the PH Lamp, Copenhagen, 1994, p. 265 (early variant of this design from the 1930s)

Overall very good original condition, with the exception of one mirror that has occasional abrasions to the edges of the rim where the metal beneath is revealed. One other mirror has several very minor nicks to the enamel paint to the outer rim. One mirror has some wear and losses to the reflective mirror backing around one of the clips that holds the mirror plate in place. One mirror is very slightly out of the round – however this is so slight that it is not immediately obvious to the naked eye. In our opinion this does not adversely affect the overall attractive appearance of the mirrors and in our opinion they present very well. This represents a rare opportunity to acquire a set of three of this model.
