i just noticed the picture of your ('Great Grandmother' on the Jenkins side of the family, ' Eva Beatrice' (nee. Nance) on the left with 4 of her children etc) and noticed the back drop, take a look at this one with my Pearce gang, its my grandad 'Jim',  his mum 'Janie' and uncle 'Stee' (Dave Parr's grandad and Mike Pearces dad) Janie had the shop now called 'Bourdeaux', anyway the backdrop is the same and I've seen it in other Gibson photos. I wonder what happened to it or is it still under the wallpaper!

Jim, Janie & Steve ('Cap'n Stee') Pearce.

Probably taken about 1924
