Hi - Thank you for your reply!
Yes have just uploaded 2 more images.
There's no glass - it looks like it in my photo but the old photo has been lacquered.
For some reason there's glue on the back - more visible in the pic just posted.
So I'm not sure if this item was intended to be used for something else, and has been re-purposed as a photo holder.
Yes - I'll leave the photo as - is - it adds so much character!
Once again, thank you for your reply!
