Seen in Cairo : The Yacoubian box

Seen in Cairo: a very old card box keeping very beautiful and old glassware owned by my late grandma in our attic aka (sandara).
The box had the sticker of “N.Yacoubian” which according to my knowledge was located at the famous Yacoubian building in Downtown Cairo.
It was immortalized infamously in Alaa Al-Aswany’s best-selling novel of the same name.
Built in 1936, the Art Deco building was named after its owner, businessman and the head of the Armenian community in Egypt then, Hagop Yacoubian.
I love the Art Deco font used to write Yacoubian in Arabic as well in English. 
I do not know if the store, which was like Tiffany's in the old golden days is still there or was closed. I will check it.
Ironically I passed through that building hundreds of times and I never thought to see it.
