Hi All,I poster some time ago, when I purchased this. It was a fragile poster in need of love. It’s now been restored, cleaned and professionally linen backed and framed. I am after some advice on thoughts on the value for my home insurance. I know this is extremely rare, the only other copy I can find is in the London imperial war museum. I’d appreciate any advice.Thankyouhttps://i.imgur.com/OfNiEgR.jpg
