Good article, thank you.  Nice block of 4!

If you take a closer view (without comparing other criteria) you will notice the fake overprint was made with a water based black color and not with the oily based black color which leave a yellow fatty impression around the overprint.

I add this comment because someone might be saying the overprint is genuine but the cancel is wrong

Very interesting blog (an nice music)! Thank you for sharing. I will read it now

About your comparsion of the stamp with the damanged "暫" please take a look on this block of six. The overprint was obviously made through a chop of two (or four).

Thank you for sharing!

I like to see you have the stamps real used, often more hard to get as mint!
