The sign was erected in the early 1950s, when the building was renovated and expanded to become the brand new Assiniboia Hotel (before later becoming the Inn). The last memories I really have of the sign being lit up were from before I left for university in 2002. I remember the yellow lights around the edge of the sign flashed in a way that made them look like they were moving. It was incredibly bright and lit up the entire intersection on South Railway Street.
Sadly, the sign has been left wasting away for years now. The fading paint only emphasizes the neglect of the building, and I can only guess how long it will be before the three story sign is removed out of fear of it falling. I hope I'm wrong. It would be amazing to see it lit up again.
