Maryland Code, Commercial Law § 17-402

“The records at (name of museum) indicate that you have property on loan to it. The museum hereby terminates the loan. If you desire to claim the property, you must contact the museum, establish your ownership of the property, and make arrangements to collect the property. If you do not contact the museum within 60 days, you will be considered to have donated the property to the museum.”.

(b) If a loan of property to a museum is not a permanent loan and does not have a specific expiration date, the property is presumed abandoned if, for at least 7 years after the date the museum took possession of the property, there has not been any written communication between the museum and the lender or lender's designated agent.
