Could it have had a different name and the artwork on the postcard of an original rendering and maybe an uncompleted building at the time and the postcards being all ovedprinted or some other type of modification...?

I would think it is the first "Thunderbird" postcard, but puzzled why no signage on either the façade or the tower.
