Although the style of the jar is the same used by Dr. Berry's ointment, the artifact found is clear glass while all of the examples of freckle cream the TIGHAR researchers have been able to find are milky white or opal glass. They have also been unable to match the exact size of the artifact jar to a known jar of Dr. Berry's product.
The reassembled artifact jar does, however, fit nicely in a box in which anti-freckle cream was marketed. The known Dr. Berry jars do not.
"So we know there was a jar of Dr. Berry's Freckle Ointment of the same size as the artifact jar, but we don't know whether it was clear glass," Ric Gillespie, TIGHAR's executive director, told Discovery News.
