Input: Consider Input: Question: How long was Frank Pick the general manager? Passage:Through his involvement with the Design and Industries Association Holden met Frank Pick, general manager of the Underground Electric Railways Company of London (UERL). Holden at the time had no experience in designing for transport, but this would change through his collaboration with Pick. In 1923, Pick commissioned Holden to design a façade for a side entrance at Westminster Underground station. This was followed in 1924 with an appointment to design the UERL's pavilion for the British Empire Exhibition. Also in 1924, Pick commissioned Holden to design seven new stations in south London for the extension of the City and South London Railway (now part of the Northern line) from Clapham Common to Morden. The designs replaced a set by the UERL's own architect, Stanley Heaps, which Pick had found unsatisfactory. The designs reflect the simple modernist style he was using in France for the war cemeteries; double-height ticket halls are clad in plain Portland stone framing a glazed screen, each adapted to suit the street corner sites of most of the stations. The screens feature the Underground roundel made up in coloured glass panels and are divided by stone columns surmounted by capitals formed as a three-dimensional version of the roundel. Holden also advised Heaps on new façades for a number of the existing stations on the line and produced the design for a new entrance at Bond Street station on the Central London Railway.

Input: Consider Input: Question: When was the local station in Chattanooga, Tennessee that Gypsy Joe appeared on on Saturdy mornings during the 1970's founded? Passage:Meléndez began his wrestling career in 1951 at age 18. During a lengthy tenure in his native Puerto Rico, he went under various monikers and learned the ropes with the likes of Pedro Morales and Carlos Colón Sr.. Meléndez made his United States debut at Sunnyside Garden in Long Island, New York in 1963. Primarily using the name Gypsy Joe by this point, he mainly worked for Nick Gulas and later Jerry Jarrett in the Southeastern region, particularly Mid-Southern Wrestling. During his Gulas run, he was often teamed with heels like Tojo Yamamoto, with whom he formed the No Pain Train, and The Cuban Assassin. He also joined forces with Frank Martinez to be collectively known as the Blue Infernos. The masked duo would attain tag team championships on numerous occasions. By the 1970s, Gypsy Joe was a local star of Chattanooga, Tennessee, regularly performing at Soldiers and Sailors Memorial Auditorium on Saturdays and appearing on local WDEF-TV. His career wasn't limited to the South, however, winning championships around the country as well as in Canada’s Stampede Wrestling.
