Strolling up to Notting Hill Gate for our Sunday morning coffee, The Man and I came across two such signs within about 200 metre.
Now an antique shop and a money exchange, this building used to be - you guessed it - a timber merchants. Hard to imagine that nowadays in posh Kensington.
Not sure if this was for an business or if it was an advert, but if you liked the 'finest ever' marmalade then you'd come to the right place.
Hankering after more signs of the times? Derelict London has some great ones on their website.
