An exhibition of personal WW1 memorabilia at the Imperial War Museum (surrounded by traffic just south of the river, beyond Waterloo). Very well laid out and displayed and absolutely fascinating. Just the right mix of text and artefacts, photos etc. And proper recognition of women and ethnic minorities who served, and of those who stayed at home. Some very poignant and moving stuff — the last letters of men to their wives and children, written in case they should die; the telegrams which announced a death; the accounts of the mothers, sisters, sweethearts who received them. 1 in 10 of men between 18 (I think) and 45 from the UK were killed or seriously wounded ( I must check that, may have misremembered) but a huge number. No wonder Edinburgh in the years after WW2 was full of elderly spinsters and widows.
Also a gallery of Holocaust paintings — quite appalling.
