Ancient Manuscript Review 101 : Antique Hijazi Quran Parchment / Vellum ( 8th Century CE)

This is Quranic verses written in Hijazi script on a brownish vellum. Acquired from an acquaintance in Paris. The vellum originally belonged to a Professor of Islamic Art. I couldn't verify the exact date of this vellum however based on the script ( Hijazi), I would estimate it around 8th -9th century CE.
This leaf contains Surah Al Araaf ( chapter 7) from verse 128 till verse 131.

Similar leaf is on display in London Central Mosque Gallery. The leaf is believed from the same source containing the same chapter but from verse 19 till 22. The website is as below :
