I wonder whose collection this was too. I could never give them up even if they were not my family.
You'd expect it's likely to come onto the market through a house clearance.
Caz, have you heard from the person you purchased the photos from to see if they have more from the same lot? I'm hoping ..... 
I did and the answer was negative. I think these are people that just go around and buy stuff to sell for profit rather than collectors.

I want to interrogate them and ask if they split the collection up (which I suspect they did), but their answer to my email was short and brief and reading between the lines it was more of your "mind your own business" response.
Not to worry, I'm more than happy with what I've got and the story behind them, well..goes without saying…AMAZING!!!
