Mr. J. A. Beveridge lived in Worcester, the commercial and educational center about 50 miles west of Boston.

In October of 1917, Mr. Beveridge received a postcard from Ruth.

Ruth was in Chicago, which she reached belatedly due to a “washout” of the rail line.

Chicago was the great center of rail transportation for the nation; thousands of travelers would be arriving each day.

The face of the postcard is an illustration of Michigan Avenue, near the Art Institute of Chicago.

Like Fifth Avenue in Manhattan, Michigan Avenue in Chicago links the city’s great cultural institutions to the premier shopping destinations.

These famous thoroughfares are lined with handsome buildings in a range of architectural styes.

This postcard view, “Michigan Avenue Looking North…”, was published by Max Rigot Selling Company of Chicago.

On the reverse, Ruth has written a message that addresses Mr. Beveridge as “Jack”.

After describing her travel to Chicago, Ruth reports that, “it is very cold and …windy here”.

Ruth expects to remain in Chicago for a week, and she plans to receive her mail “General Delivery” at the Post Office.

In closing, Ruth thanks Jack for his card and “the diagram of Ayer”; it is unclear what Ruth received from Jack – there is a town of Ayer not far from Worcester.

Ruth concludes her message by expressing “Love”.

One hopes that Ruth found her visit satisfactory, that she did not experience delays in her return, and that she and Jack remained friends and correspondents for many years.

Jack preserved the memento of Chicago throughout his life.
