According to the SCA website the block was spotted in the Alexandra Irigoyen Art Gallery in Madrid.
On March 19th, 2009, Dr. Josep Cervello from the Universitat Autonoma de Barcelona sent an e-mail to the Secretary General of the SCA expressing his concern about a limestone block that was then on display in the art gallery of Alexandra Irigoyen in Madrid.This story had been spotted in anonymous form by the same group of students. But now we have further detail:
Dr. Cervello also was able to ascertain that the piece belongs to the Galerias F. Cervera in Barcelona.This is the same Barcelona galerista linked to the Egyptian coffin seized in Miami. Barcelona has also been the location of seizures during Operation Ghelas.
I presume that the Barcelona galerista will be providing the SCA with full information as part of their enquiries.
