IMG 0912-001-Ghostsign Palimpsest

Two signs, one painted over the other, fading at different rates. King's and Bates's were owned by the same company. One sign reads:

KING'S
Tartaric
Fruit Salts
for
Gout and
Rheumatism

BATES'S
Salve
Cures
Wounds
& Sores

The other says (more faded at the top left due to how the sun hits it):

THE
RENOWNED
SALVE
for WOUNDS & SORES
OF ALL KINDS.
80 YEARS
_______
ALSO FOR
KING'S
CITRATE OF MAGNESIA
INVENTED IN 1844
The ORIGINAL SAFEST
& BEST
