The Legend of Zelda (1986 - released 40 years ago today) sprite table (presumably for memory allocation purposes) and enemy character progression sheets, all drawn by Shigeru Miyamoto.
This overlay shows how minor modifications were made between planning and implementation, such as the addition of the fire and narrowing of the entrance/exit.
Can't remember which interview it came from (maybe an iwata asks) butIirc the map was drawn with tezuka and miyamoto sitting side by side, with tezuka handling the left half and miamoto the right half
