Ideas for 'Collections'

I have been working on ideas for a collection but am not happy with my idea for a composition so will have to re-think!
These are only rough drawings and show some ephemera that I have found during various visits to Greece.
They include a tiny clay type figure found among stones on a beach. I showed it to the island's museum but it was not of interest to them. I still don't know if it's old or modern.
The paper boat I found on a pavement in Athens and I like the idea of sending it off on its travels again!
