Reportedly the best-selling poster in The London Transport Museum Shop.
"My 'Old Faithful' has always been a great door opener, conversation starter, (and job getter) and I'm proud and delighted it's appeal has not dwindled over the years as it approaches its 25th anniversary. The curator informed me that it had even been a major influence on a second, more recently commissioned poster, the Rorschach Test map by the artist Cornelia Parker."
Quoted from 25 years down the tube, on David Booth's blog.
The original artwork can be seen in the London Transport Museum.
