Vintage Japanese Tea Cup 1978 Commemoration Graduation Fight Song

When I put the cup through a translation service, it says that it was donated to Osaka Prefectural Ibadara High School for graduation commemoration. March 1978. It appears to feature the schools fight song. Item is in used, vintage condition. There may be small signs of wear due to age and use. Please examine the photos carefully as I have tried to faithfully document the items condition. Feel free to reach out with any questions.
