The H. Callcut & Son sign that once adorned this house front has now been whitewashed (see below). It was on Blackstock Road in North London, close to my old primary school, so I was quite sad to see this familiar landmark lost to property development. The photo above, and the details below were taken in 2014. Comments on this blog post suggest that the sign was retouched at some point. RIP.
And finally, a photograph that I think dates to c.2006.
