NO CAPS REQUIRED. Letters "a-w" is from the 1984 version of the show, while "x-z" is from the 2009 version of the show, as well as the numbers. The "y", however is slightly altered, because it was identical to the '84 version of the alphabet. The capital "V" makes the Visitor's insignia.
It's been some time since I was on this site. The lowercase only use top slopes, while uppercase uses top and bottom slopes. The numbers use pairs of slopes that move in the same direction.
This is a font.
