Looking at the catalogue
The design of a stamp is a description of the graphical
elements of the stamp.
The design refers solely to the overall graphic appearance of a stamp. Allowed variations among several stamps of the same design are only the denomination, other inscriptions including issuer name, function, and imprint, and any variants.
The design description is a shorthand for the graphical appearance that identifies it unambiguously. The software will accept any phrase, but it works best to use brief but suggestive descriptions. For instance, "Queen Victoria 1840" is a good description for the design shared by the Penny Black, Twopenny Blue, Penny Red, etc. Although seemingly too brief, "Stanton" is sufficient to describe the design shared by all the US stamps of the 1870s depicting secretary of state Edwin Stanton.
It is acceptable to use generic terms, such as "numeral", although less useful since there are a great many different designs based on a numeral. Oftentimes these can be made more specific by describing additional graphical elements, for descriptions like "numeral in oval", or "slanted numeral".
(In the Scott catalogue, designs are described with "A" prefixes, as in "A58", while Michel uses lower-case letter combinations, as in "bn.")
(add a designer)
Each design has its own dedicated page. This page lists all the stamps using the design, and displays images of stamps that have images.
You can edit both short and long descriptions on this page. Note that the changed short description affects the display of all stamps using the design; if you want a different design for a stamp, edit the stamp on its page and simply type in the design description.
If a design is not being used by any stamp, it may be deleted.
