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.

These background tile-sets and level layouts were also reportedly drawn by Miyamoto...

Some more background planning sheets...

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.
