100 years Bank of China in Hong Kong (part 2)

According to this article the Bank of China Hong Kong will issue a commemorative note in September 2017, celebrating the opening of the first branch of the bank in Hong Kong in 1917. There were rumours about this note circulating last year but it seems they might have had the issue date wrong, since the 100th anniversary is being celebrated this year.

"Bank of China Hong Kong will offer three types of notes (single notes, three-in-one uncut notes and 30-in-one uncut notes) (...) the number of notes to be issued will be a record high – substantially more than the two million HSBC issued two years ago."
