The famous "It's dangerous to go alone! Take this." scene of The Legend of Zelda was quite different during development.
In this image, the old man in the first cave gives Link the option between a sword and a boomerang. The old man's message is different as well. Instead of saying "It's dangerous to go alone. You may have this." he says "It's dangerous to go alone. Take whichever weapon you prefer."
The layout of the cave also differs - the old man and the flames are not aligned centrally within the room, and the flames are placed one block closer to him on each side.
This image also appears on page 41 of the NES version's manual, but with the Japanese text blacked out.
