Item Description

This is an original maritime painting by John O'Hara Cosgrave II (1908–1968), an American artist best known for his detailed depictions of naval and merchant marine subjects. The painting features a dramatic scene of a clipper ship under full sail navigating through choppy seas with another vessel in the distance. Cosgrave’s works often capture the spirit of seafaring with historical and artistic accuracy.

This example demonstrates his characteristic attention to detail in the rigging and sails, along with his dynamic rendering of ocean waves. The greenish tonal palette and careful linework are consistent with his mid-career works. The composition is balanced, and the signature is in a familiar style and location consistent with authenticated Cosgrave paintings.

Artist Background

John O'Hara Cosgrave II was a respected maritime artist, illustrator, and son of Irish-American artist John O'Hara Cosgrave I. His works appeared in naval publications and exhibitions, especially during and after WWII. Cosgrave II’s paintings are held in both private and institutional collections, including some naval museums and archives.

Condition Notes

• The painting appears to be in excellent condition with no visible water damage, foxing, or fading.
• The frame is solid and carved, with minor wear consistent with age.
• The back shows canvas tacking and an aged wooden stretcher consistent with mid-20th century mounting techniques.

Authentication

The painting bears a visible and stylistically accurate signature. The rendering quality, subject matter, and materials all align well with Cosgrave's known works. However, due to the presence of many unsigned or misattributed Cosgrave paintings and reproductions, a formal authentication through a maritime art expert or auction house (e.g., Bonhams or Skinner) is advised for maximum value realization, especially if preparing for sale.
