Yes. An Antique is designated as being 100 years or more. Every item on this site pre-Genocide and Antique.
100% of the Kutahya ceramics, Marash Embroideries and the MetalWorks items were made by Armenians. Only a few of the rugs might have been made by non-Armenians.
Some were purchased from private collections around the world. But the vast majority were purchased from Turkey.
