I'm sure the contract between the museum and the Egyptian government is explicit... you have our permission to explore and recover lost or unknown artifacts, however what ever you find belongs in all aspects to Egypt. My guess, the museum never consulted with the SCA on the intention and representation of artifacts used in the exhibit. I applaud Egypt for not allowing cultural appropriation in any context; modern music by Beyonce, Tina Turner and Nas have absolutely nothing in common with ancient Egyptian music or culture.
