Ask Mr. Foster was a travel agency located in downtown Hill Valley in 1955 and in 1985. In 1955, the agency also had a sign advertising " fabulous 10-day vacations in Cuba ", something that was no longer possible for American travelers by 1985. The advertisement, visible in footage cut from the first film, can be seen from a distance in the second film. By 2015, the local office has been replaced by Uniglobe Travel agency. Advertisements for travel to Vietnam ("Surf Vietnam"), like those for vacations in Cuba, also refer to what would have been, in 1985, unlikely travel destinations.
