ANOTHER THEFT AT MOBA!
This piece has been stolen from the MOBA gallery in the Somerville Theatre. It was on display for informational purposes only, as we do not include paintings on velvet in the collection. This is the second theft this year; it's getting annoying. If you are the selfish lout who took it, or have information about the piece's whereabouts, please contact: firstname.lastname@example.org.
