Hidden Elements and "secret Marks"
Sometimes designers include tiny elements into a design, sometimes at the request of the stamp-issuing authority, sometimes on their own. Stamps may have a year or name worked into a design, while the US stamp honoring Rabbi Bernard Revel has a minute Star of David visible in his beard.
Secret marks are small design alterations added to distinguish printings unambiguously. These usually take the form of small lines or marks added to clear areas of a design. Chinese stamps of the 1940s have secret marks in the form of slightly altered characters, where two arms might be changed to touch, when previously they were separate.

“English general and singular terms, identity, quantification, and the whole bag of ontological tricks may be correlated with elements of the native language in any of various mutually incompatible ways, each compatible with all possible linguistic data, and none preferable to another save as favored by a rationalization of the native language that is simple and natural to us.”
—Willard Van Orman Quine (b. 1908)
“They are a very decent generous lot of people out here and they don’t expect you to listen.... It’s the secret of social ease in this country. They talk entirely for their own pleasure. Nothing they say is designed to be heard.”
—Evelyn Waugh (1903–1966)
“What is clear is that Christianity directed increased attention to childhood. For the first time in history it seemed important to decide what the moral status of children was. In the midst of this sometimes excessive concern, a new sympathy for children was promoted. Sometimes this meant criticizing adults. . . . So far as parents were put on the defensive in this way, the beginning of the Christian era marks a revolution in the child’s status.”
—C. John Sommerville (20th century)
