Acquiring Title to Undocumented Property.
Property in the possession of a museum for which the museum does not know the
owner or have any reasonable means of determining the owner becomes the
property of the museum if no person has claimed the property within 7 years

the owner of the property on the day after the 7-year period ends, free from
all claims. This Section does not apply to stolen or confiscated property.
