Miss Mary Singer lived in Columbia, the borough that became center of transportation and commerce on the Susquehanna River in south-central Pennsylvania.

In July of a year near 1910, Mary received a postcard from her friend, J. H. Gates.

The postcard was mailed from some other town in Pennsylvania; the postmark is very indistinct.

The face of the postcard is a comic drawing of chalk messages and doodles, sometimes crude and misspelled, on a classroom blackboard.

The drawing is entitled, “School Days”.

The postcard was published by the renowned English firm of Raphael Tuck & Sons.

(This theme of childish ignorance and misunderstanding can be found on many other comic postcards.)

On the reverse, the sender asks eagerly for the address of S. Elslager.

Apparently, a postcard sent to S. Elslager was not answered, and the writer of this postcard hoped to learn “where S. Elslager is staying”.

From the theme of the postcard, and that the friends were trying to contact one another during the summer, I suspected that all the parties were classmates.

One hopes that Miss Singer had the requested information, that J. H. Gates was able to correspond with S. Elslager, and that all the friends enjoyed a wonderful summer.
