You know, it's the little differences. Like how everywhere else online that mentions this large, 1979 print by Mexican surrealist Pablo Friedberg calls it Alfabeto Inhabitable, not Halfabeto And how I guess I forgot that the Spanish alphabet doesn't have the letter I, and L is double. Maybe forgot is not quite the right word.
