Boston Navy Yard work crew on ship Mt. Vernon
Work crew of a dozen men (including Matthias Cavanaugh, center, balding) at Boston, Mass., Navy Yard. Note on back says "Taken on deck of Mt. Vernon - Innsburg[?] job 1944."
All in picture are a mystery -- save my former, since-deceased uncle, Matthias (or Mathias) Cavanaugh, b. 1902. He apparently was in charge of this work crew. Ship is identified only as Mt. Vernon. Most likely USS Mt. Vernon...
