The Brand for Quacks

Perhaps one of the most ingenious devices in the art of quackery is that by which a well-known medicine, bearing Parr's name, is vaunted to the public as the mysterious preparation by which he was enabled to attain the extraordinary age of a hundred and fifty-two.
The portrait which is frequently attached to the puffing placard advertising these drugs, is derived from a likeness of Old. Parr, drawn by the celebrated painter Rubens.
