As seen in the original front and back of the photo, Grace has Woody Woodpecker sitting on her shoulder and a copyright 1957, Walter Lantz Productions mark at the photo's lower left. We all love Woody, but he's far too large to be considered de minimis. Woody was removed from the photo along with the Walter Lantz copyright marks. The photo of Grace without Woody is in the public domain.
Note that it may still be copyrighted in jurisdictions that do not apply the rule of the shorter term for US works (depending on the date of the author's death), such as Canada (50 p.m.a.), Mainland China (50 p.m.a., not Hong Kong or Macao), Germany (70 p.m.a.), Mexico (100 p.m.a.), Switzerland (70 p.m.a.), and other countries with individual treaties.
