The Sloop Via Old-Timey Chicago Postcards

Found this link recently of some old-timey postcards of Chicago.  Some include shots around the sloop and are always fascinating to look at.  Via Chicago Magazine:

See Mid-Century Chicago in 20 Vintage Postcards A collection of linen postcards from 1930 to 1945 shows Chicago not exactly as it was, but as a visitor would want to remember it.
