Other names for this style are, in alphabetical order: Amish beard, chin curtain, Donegal, Lincoln, spade beard, and whaler. Depending on the style, there are subtle differences in the shape, size and general manageability by each style. The Shenandoah, specifically, tends to be somewhat longer than the thin chin curtain. The thin chin curtain beard is a particular style of facial hair that grows along the jaw line and covers the chin completely. This is not to be confused with the chinstrap beard—a similar style of beard that also grows along the jaw line but does not fully cover the chin. In addition, many thin chin curtain beards do not extend that far below the jawline, if at all, whereas all chinstrap beards generally do.
This style of facial hair was made famous by individuals such as Abraham Lincoln and C. Everett Koop. In Spain, it could be largely associated with 1970s progres and other cultural icons, such as writer Álvaro Pombo.
