Great piece of local baseball history. 

On back, the handwritten notation says:

• "West Shore Champs (11–2)" (11 wins, 2 losses)
• Absent: Thompson
• Framed by Miller's Craft Shop, 412 A Street, Carlisle, PA, which was in business during the 1950s–1960s.

The roster written on back appears to be:

Top row (left to right)

• D. Eugelbach (or Euglebach)
• F. Jackson
• J. Boomershine
• C. Fitzpatrick
• F. Lambert
• D. Wagner (Mgr?)
• Mr. Bowman (Coach)

Middle row

• S. Baljen (uncertain spelling)
• M. Timmer
• B. Larsen
• B. Snyder
• D. Bigler
• D. Halpin
• S. Hockley (or Hackley)

Front row

• B. Brennemen (possibly Brenneman)
• B. Geery
• B. Deibert
• S. Yinger
• D. Boomershine
• J. Lane

Several of these surnames are well-established Cumberland County/Carlisle families:

• Boomershine – an uncommon surname that appears in Carlisle-area records.
• Bigler – longtime Cumberland County family.
• Halpin – Carlisle-area surname.
• Geery – found in Carlisle school and newspaper records.
• Snyder – common locally.
• Yinger – Cumberland County family.
• Brenneman – common in central Pennsylvania.
• Hockley– likely Hockley, another local family.
