... Purchased at auction from Spectrum. When the bottle arrived I noted that it also had an Acker Merrill auction sticker...
One can't help but wonder whether the previous owners of the bottle knew it was bad and chose to sell it to another victim. May the fleas of a thousand camels infest their armpits.
My costliest bottle of drain cleaner was a 1967 Lafite Rothschild, also an auction purchase.
