Korea Cover 1921?

Dear all

I found it in korean local auction.
I didn't see this stamp before.
It's genuine or forgery?

May we have a close up, of the stamp please?

Are you wondering whether it's a forgery simply because you haven't seen it before? Or because, there's something about the stamp that makes you question its authenticity?

Your image is still not of sufficient clarity to make a proper appraisal.

I do not recognise it.
The perforations (if, indeed they are ) are right dodgy.
Looks like pinking shears.

Have you sought explanation from the vendor?

Keep us abreast of developments.

Doji - Are you certain of the date?

1921 is printed at the bottom left of the stamp, but 1921 was during the period of Japanese colonial rule, so at that time Korea wouldn't have been producing postage stamps inscribed in Korean in the hangul alphabet and denominated in chon (jeon), as this one is. Korea used Japanese stamps during that time.

The hangul characters to the right of "1921" read (from right to left) jyo-seon-u-pyo (Joseon postage stamp). The word directly below the butterfly is na-bi (butterfly).

Fabulous research Erilaz

Joseon / Choson Dynasty. The Joseon dynasty (also transcribed as Chos#335;n or Chosen, literally translated as#8201;Great Korean Country) was a Korean dynastic kingdom that lasted for approximately five centuries. Joseon was founded by Yi Seong-gye in July 1392 and was replaced by the Korean Empire in October 1897. It was founded following the aftermath of the overthrow of Goryeo in what is today the city of Kaesong. Early on, Korea was retitled and the capital was relocated to modern-day Seoul. The kingdom's northernmost borders were expanded to the natural boundaries at the rivers of Amnok and Tuman through the subjugation of the Jurchens. Joseon was the last dynasty of Korea and its longest-ruling Confucian dynasty.

1921 remains curious as the Joseon Dynasty ended 1897

Could the label show the ancient images of Joseon Butterflies
as shown on some antiques ?
They may have meaning, that is lost on me.

Perhaps when the candles are lit, creates magical shadows ?

There was a Korean Gouvernment in exil in Shanghai starting in 1919.The first president was Syngman Rhee.Could be a local production of this cinderelle stamp?

Regarding the butterflies: perhaps in their original state, the purpose of the polished bronze butterflies was to serve as reflectors, to amplify the light given by the candle flame.

Great suggestions !
All we need now, is for someone to read (or try to)
The Postmark
The written word.

For the record, I had checked all Japanese revenues and seals I had
Nothing even close.
I had thought maybe a silk moth rather than a butterfly.
