A couple of comments about the prototype.
Awnings, as I remember them, weren't more than 10' -12' wide. Long store front names were made on several awnings. This is not to say there weren't longer ones, but I never saw any.
The reason, I believe, for the shorter awnings was that they got very heavy, especially when wet, and the crank mechanism, and they person using it simple couldn't handle the great weight of a large wet awning. I still remember the local grocer cranking his down in the morning and up at night.
As a young kid we would get some new kid to stand out in front, "to make sure everything was OK", and we would make sure he was standing in just the right place. We would then crank the awning down as fast as we could. There was usually some moisture collected in the awning overnight and we'd give the new kid a bath!
Needless to say, I had been the new kid, once.
