Richmond, Va. ? Two Civil War-era dolls thought to have been used to smuggle medicine past Union blockades were X-rayed Wednesday, disclosing hollowed papier-mache heads that once could have contained quinine or morphine for wounded or malaria-stricken Confederate troops.

The 150-year-old dolls, dubbed Nina and Lucy Ann, were likely packed with the drugs and shipped from Europe in the hope that Union troops would not inspect toys when looking for contraband, a museum official said.

Nina and Lucy Ann were taken to VCU Medical Center from their home next door, The Museum of the Confederacy, to see if the contours inside their craniums and upper bodies were roomy enough to carry the medicines.

The conclusion: yes.

The next step could be forensic testing for any traces of the drugs.

The dolls were given to the museum by donors who said they were used to smuggle medicine past Northern blockades to Southern troops.

Nina was donated to the museum in 1923 by the children of Gen. James Patton Anderson, who commanded the Tennessee Army of the Confederacy. She has red felt boots.

Lucy Ann, attired in a salmon-colored cape and dress, was given to the museum in 1976 by an anonymous donor. She is adorned with a coral necklace.

Lucy Ann has an open gash on the rear of her bonneted head, possibly made when its contents were emptied. Nina was likely disassembled then stitched back together.

Museum officials believe the dolls were in fact used for smuggling in the Civil War.
