In December of 1909, Robert was in London – the largest city in the world at that time.

Robert sent a postcard to Miss Mary Burgess of Boston.

The face of the postcard is a photograph of Hyde Park, the largest of the string of parks and green spaces that stretch from Kensington Palace to Buckingham Palace.

(In 1536, King Henry VIII seized the land from Westminster Abbey to become a royal hunting ground; it opened to the public in 1637.)

The photograph was clearly taken in warm weather, as men and women are wading in the basin of The Serpentine.

The Serpentine, at forty acres, is the larger of two lakes within Hyde Park.

The postcard is numbered, and there are initials L. L. – which might make it possible to identify the publisher.

On the reverse, we learn more about the Robert’s trip.

It seems that he enjoys adventure as he writes, “I am out on my travels again.”

Robert is traveling with “Sinclair of Maryland” and the pair are staying “out in Kensington”.

Kensington, once a rural manor, is now a very affluent Royal Borough entirely contained within London.

(It is 2.9 miles west of Central London.)

The accommodations appear to be a private lodging as Robert reports, “our host being a retired sea captain.”

The stay in London is almost ended as Robert and Sinclair will “move on tonight”.

One hopes that Miss Burgess was pleased by the picture from London, that the travelers had many further adventures, and that they returned safely to their homes.
