“L'essentiel du fonds avait été liquidé mais il restait quelques vinyles, coffrets et une importante collection d'affiches et de tee-shirts qu'il s'était refusé à brader avec le reste.” — Most of the stock had been sold at a knock-down price, but there was still some vinyl, a few boxed sets, and an extensive collection of posters and T-shirts he had refused to sell off cheap.
