Can anyone guide me on what to do with this embroidered cloth relating to the South African Railways & Harbours?

I have uncovered an embroidered cloth with over 50+ signatures on - it relates to the SAR&H (South African Railways & Harbours) from 1918. It was done by my great grandmother and apparently relates to the Bloemfontein siege (or the men from World War 1). I've attached photos for a broad idea.

Can anyone point me in the direction of what to do with this cloth. For me it belongs on display be it a digital platform or in a museum.
