I think a cropped version of the cover photo from Alistair Anderson's Alistair Anderson LP would make a wonderful example.
Could someone contact him to see if he might share a copy of the original photo?
Apparently requests from the organiser have already been made made to AA and the EFDSS regarding concertina images, with no response from either. This was the reason for launching an appeal through this forum.
I have just had a message to say that Hubert Boone now has the images he requires for his exhibition.
A big thank you to those who responded so promptly to this appeal, it is very much appreciated.
