Next Tuesday - 15 May - I'm giving another postcard tour of Waterstones Gower St in London.
Last time we were helped on our way by George Orwell, Gillian Wearing and E.M. Forster.
This time, we'll be stopping off in the poetry section. And the man, Roland Barthes, is sure to get a look in too.
The tour is something of a walking essay.
With the help of the books on offer, we'll try to make sense of why old postcards are intriguing. Last time we talked a lot about the parallels between collecting secondhand books and the habit of amassing postcards.
Starts at 6.30pm in the secondhand book department on the first floor. Tickets can be bought from the shop.
Then next Friday - 18 May - I'm talking about the history of postcards at the opening of the British Postal Museum & Archive's new exhibition.
The Post Office in Pictures is at the Lumen Gallery and runs until 31 August.
No tickets needed for this one.
