Said the Scarecrow to his personage:
"Show us at once to your master, the Emperor."
The man looked from one to another of the party in an embarrassed way, and finally answered:
"I fear I musy ask you to wait for a time. The Emperor is not receiving this morning."
"How is that?" inquired the Scarecrow, anxiously. "I hope nothing has happened to him."
"Oh, no; nothing serious," returned the man. "But this is his Majesty's day for being polished; and just no his august presence is thickly smeared with putz-pomade."
Still in use 100 years later by citizens of the real world to polish printing plates to remove small abrasions before printing. It is also used for cleaning other printmaking equipment and for deep cleansing before color changes on a printing press.
Commercial printers use Putz Pomade to maintain expensive printing equipment that uses etching processes similar to what fine artists use in etching and intaglio methods. Putz Pomade is available in past and liquid form. A 15 ounce tin costs between $12 and $25, depending on source. Valley Litho Supply seems to have the best price.
