Well, today, at number seven on Time Out's 'Top Ten London Car Boot Sales', no less, there was disappointment. The 'huge' weekly market, at St Augustine's School in Kilburn, was all about the tat, not much about the treasure.
However, I did find these tacky but John 'Boring Postcards' Hinde-esque photo coasters - late 1960s tourist images of rural Spain. Nice font, too. I couldn't decide if they were awful or lovely. That seemed like a good reason to buy them. They cost me all of £2.
