Client: Central Vermont Railway (owned by CN) Design: James Valkus and Allan Fleming (?) Date: Unknown [](http://canadiandesignresource.ca/logo/cv-rail/attachment/cv-2/) In one of the opening scenes of the season 5 premier of Mad Men, the CN logo can be seen in the background on a poster, with a “CV” logo underneath it. A quick google search identifies this mark as Central Vermont Railway, which the CN took ownership of in 1923 and sold in 1995.
