Miss Clara Brennan lived in South Langhorne, now the borough of Penndel in Bucks County, PA.
This area of southeast Pennsylvania was first settled by English Quakers and remained an agricultural community until 1876 -when the Philadelphia Reading Railroad connected the village to both cities.
South Langhorne was a part of the adjoining town of Langhorne until building lots were sold under the name of “Eden”, and a new Post Office was built and named “Eden”.
There were other name changes as the borough grew; “South Langhorne” was adopted to replace “Eden” in 1911.
In 1947, the name of the community was changed once more to “Penndel”.

In September of 1912, Clara received a postcard from her friend, “M”.
The friend mailed the greeting from Atlantic City, the popular vacation destination in east central New Jersey.

On the face, a photograph shows a vast throng crowding the Boardwalk of this resort town on the Atlantic coast.
The humorous caption reads, “The crowd that met me at Atlantic City, N. J.”
The comic suggestion is that the multitude had turned out to welcome the visitor.
Humorous greetings such as this were printed for many destinations – I have examples from train stations and from piers that show crowds ostensibly waiting there to meet the writer.
Many of the other postcard examples refer to the crowds as “a few friends” or “my best pals”.
On the reverse, M writes, “Arrived safely -the weather is fine.”
The sender adds, “Wish you were with us.”
Miss Clara preserved the vacation souvenir throughout her life.
One hopes that she was able to enjoy the amusements of Atlantic City at some time in the future, perhaps when it was less crowded.
