Site: June Aylward (1 memorial)
W11, Portobello Road, 115
The London Compendium gives 1950 as the year in which Aylward opened her shop, while Wikipedia reckons "antiques dealers arrived in the late 1940s and '50s". Whatever, it's been a lively antiques market for as long as most people can remember and this plaque has been here since at least 2005.
