Brain storming ideas for Type Specimen

I have begun to brain storm ideas on how my typeface could be shown as a type specimen; the original idea was to create an A2 poster based on the idea of tube maps (layout and colour wise) in particular; the route lines. The typeface in large and small scale, descriptive words to describe 'Anfractuous' ,the rationale and the typeface a-z would be displayed on the specimen.

However this idea changed as it was too much content to pack into one A2 poster; the idea changed when briefly trying the idea and discussing with Ben;

-A1 size poster instead of A2
-The A1 poster will be folded to work as a double page spread as well; the inside would have the regular a-z version on one side and the light a-z version on the other
-More minimal and professional approach
-Digital printed cover, screen printed inside
-Narrowing the colours down to red and yellow (most popular tube colours) keeping black for the rest of the basic text and type face
-Narrow the 8 descriptive words down to 4;  for more space
-The descriptive words to fit within the tube route lines
