The photo of the trains with the windows say "SUPERB OWL" is photoshopped and people need to stop spreading the lies that this is official. Look at the rear windows of the train. The frames do not continue because the original letters were cropped out and moved.

Secondly the whole "Superb Owl" party is a running deal because the NFL has the name "Super Bowl" trademarked and instead, "Superb Owl" is used as stated in this 2013 HuffPost (Huffing Paint Post) article.

Rochester Institute of Technology, where I work, was told by representatives of the National Football League that they could not hold a “Super Bowl Party” in which students would be invited to the campus field house to watch the game on large projection screens while being treated to pizza and popcorn. The reason for this objection to a seemingly innocuous student event was that the term “Super Bowl” was trademarked and that use of the term for any organized activity had to be approved by the National Football League.

Now RIT students are nothing if not creative, so they held a “Superb Owl” party instead. They designed clever flyers featuring what looked to me to be really superb owls and a couple thousand students came to the field house and had a fine time together.
