Great find Jeff.
According to
this 2012 article, "The current record-holder, the “international” version of the Metropolis poster – the same Heinz Schulz-Neudamm design as number 3 minus the German writing. The clean lines and delicate shading make this a wonder to behold. It sold for $690,000 in 2005; the rumoured purchaser was Leonardo DiCaprio."
This new 2017 article says "The feds are also eyeing other assets, including a rare movie poster of Metropolis purchased by Aziz for $1.2 million in October 2012 that was described as hanging in Red Granite's office. According to a source connected with Red Granite, the poster has already been turned over to authorities."
So presumably these articles are referring to the same poster?
