Ae Marks
An ae-mark sheet uses four lines to state its scope.
The first line states the cases the mark covers. The second line states the cases it leaves out. The third line is the day it was written. The fourth line is the day it closes. The close day is not a delivery date and it is not a license expiry. After that day, a reader should not treat the sheet as the current mark. This page does not sell a typeface, and it does not offer the æ as a trademark service.
All four lines are present.
After the close day, the sheet stops.
Do not call the close day a delivery date.
Do not sell a typeface.
