On Monday, the Olmsted Historic District sign was on the ground in the traffic island at Paradise and Walker Roads.
Tuesday it was gone.
Where it ended up is a mystery.
The town planner checked with the Department of Public Works and Police Department officials but they have not heard what happened to the sign.
Somebody might have cleaned it up, seeing it was on the ground.
If so, Town Planner Pete Kane would like to where it is now.
He asks anyone who has it or knows where it is to call or email him — -781-596-8829 or firstname.lastname@example.org
If the town recovers the sign they can gauge its condition and see about repairing it and returning it to its previous spot.
The sign may have been hit by a vehicle.
The white sign is one of two in town welcoming visitors to the Olmsted Historic District.
The other sign stands on the Town Hall lawn near the corner of Burrill Street and Monument Avenue.
Together they mark the subdivision laid out on the former Mudge Estate by Frederick Law Olmsted, said Swampscott historian Lou Gallo.
Olmsted also laid out The Emerald Necklace in Boston and Central Park in NYC.
The district is listed on the National Register of Historic Places.
