Interesting Vintage Otis Escalators - Hudson's Bay - CF Polo Park, Winnipeg,

These are some amazing vintage Otis escalators. These are interesting escalators because the 2 top ones have a very rare "Otis Escal-aire" logo on them and the 2 bottom ones have the regular "Otis Escalator" logo. I think Otis Escal-aire might have been some rare type of escalator that Otis used to make.
