The artworks by renowned equine artist Franklin B. Voss depicted foxhunting scenes, perfectly blending into the ambience of the private club known for its history of foxhunts and steeplechase races.
On Jan. 18, 2006, both paintings disappeared.
They have not been recovered.
Police said the paintings might have been carried out of the club between 5 and 9:30 p.m. that day by two thieves posing as service workers.
They suspect two men wrapped the paintings and other artwork in Persian rugs and carried them outside to a van. Unsuspecting club employees thought the carpets were scheduled to be cleaned, police reports indicate.
The estimated value of the haul was $68,000.
Township police Chief Michael Matrunics said leads have evaporated during the past five years.
