Not the best shot, taken with my phone. Will have to come back to reshoot.
Some history:
Harbisons Dairies built the water tower around 1914. There were two other bottles at the intersections of Kensington and Erie avenues and another at York Road and Ontario Street in Kensington. it was a water tank for the sprinkler systems.
Over time, the milk bottles became trademarks for the company. When the original milk bottle and the plant that it was attached to were sold to the Novick Brothers food company (for a mere $40,000 in 1951), an agreement was drawn up: The water tower was to remain and if the shape was not changed, the plant's new owners were allowed to paint it any color but white. It took a while, but eventually the agreement was honored and the bottle was painted gray and black.
Today, Harbisons Dairies are no longer in business (the company was sold in 1966), and all that remains is the original bottle, rusted and in danger of meeting the same fate as the other two. The bottle, nominated to the Preservation Alliance's Endangered Properties List in both 2003 and 2004 is said in the alliance's newsletter to be "not as significant as many other sites.

"Berger Bros. Company"
The origins of Berger Bros may be traced to the late 1800s. William H. Berger was born in Milton, Pennsylvania, in 1841. He learned carpentry before joining the Union Army during the Civil War. After the war, Berger moved to Philadelphia and in 1874 he founded William Berger & Company, manufacturers of tinners' and roofers' supplies such as copper, aluminum and steel gutter. Soon after he was joined by his brother, and the company name was changed to Berger Bros Company. The company grew steadily, and became one of the largest of its kind in the United States. It is still in business today, operating outside the city limits in Feasterville.

Older, painted brick signage. Taken 1929.


An early location of the business seems to have been immediately adjacent to the Betsy Ross House, in a building now demolished. First image taken 1929, next two, dates unknown.

Sign on larger building, with dimensional lettering in place. Taken 1959. The larger building next door to the earlier location still retains the ghost outline of lettering left after dimensional tin letters were removed.

Older, larger sign with "Esslinger" script, covered by newer, yellow-background sign.
Another sign appears far beneath, the only remaining legible section reading "... & SON."

This could be a remnant of G. Dallett & Son Co., a candle and soap works that occupied the corner space until moving further up Ridge Avenue in 1880. Archival illustration depicts both George Esslinger’s Brewery & Lager Beer Garden and Dallett’s Soap & Candle Manufactury as neighbors on this corner in 1884.
To get a sense of the Esslinger script and color pallette, look at these items: <a href=" target="_blank" www.usbeerstuff.com="" />beer label, beer can, Quizzie case, serving tray, menu sheet, and model delivery truck. For some history on Esslinger's, see here.
