Railway Station Transport Guard USA Rush Hour Art Deco Postcard

VF3   This is an undated modern postcard circa last decade of this stunning front cover to this American arts & culture magazine from 1919 and shows a transport guard (appears to be a railway station) as all the commuters leave the station and head to the streets in what I have been advised is an art deco painting to advertise the magazine of the 1919 era - I was also told this image quite famous and is called "The Crowd" but I know very little about it other than its great character - it seems an official magazine souvenir with artist details & date information of this historic cover on reverse and it is unused and mint..
