Commutation Row, Philip G Mayer
Philip G Mayer's flickr photostream contains some great early 1980s photographs of Liverpool, including this one of Wellington column outside the Walker with the row of buildings that were demolished to make way for Commutation Plaza.
Philip has also set up the Old Liverpool pool, inviting anyone with a Flickr account to post their photos to it. The pool includes this great set of postcards that he dates to around 1906 - I love the Prince's Avenue and Bold Street ones. The postcards are all based on original photographs. There's also a very stylish artist's impression of the interior of the Mersey Tunnel and a set of photos of the last night of Woolton Cinema.
