Bartholomew's street maps of London - 1930s - 40s, tenner each

[malumbu]

South East, South West and North East Sections. Seen them on sale for ?25 each but I doubt whether they are particularly collectable: https://www.abebooks.co.uk/servlet/SearchResults?an=&tn=bartholomews%20street%20index%20plan%20london&cm_sp=mbc-_-ats-_-all

Tenner each or all three for ?25

The link has representative pictures.

They will have been opened only a few times, but don't have practical use as they will get quickly damaged. The NE one is a little grubby and missing the back cover, but complete. The other two are very good for the age. They will be as good or better than those advertised in the link.

They postdate 1936 when Crystal Palace burned down, and predate the nationalisation of the railways in 1948, and cost 3 shillings at the time, around ?8 in today's money

I'd mount them and use for cosmetic purposes eg in a community building, shop or pub. But they could look nice in your home too, certainly very interesting. Mounted I expect they would be more valuable too.
