In the Bookshops of Arkham, an eight-hour YouTube series of Call of Cthulhu ‘actual play’. Just in case you were curious about such RPG things.
And, as for props for such things, I found a nice 1904 card which might serve to aid in visualisation of settings. The shop on the right of the row being a possible book shop.
It’s a pity that city bookshops and galleries don’t (didn’t) get photographed, as 80 or so years later they’re of great interest due to their connections with famous writers and artists.
