Photo Number Twenty-One

Jack was in the Army during WWI.  This photo was most likely taken in 1917 or 1918..probably in 1918 since it says on the photo. " Taken after one year of service overseas." And then something in the same handwriting below Sincerely, Jack..that is really hard to make out ( Geo Sister mor)??   The photo was taken at Temple Studio in Waukegan, Ill.  Off to the left is this information: US 28 General Hospital Ward 49 Fort Sheridan, Ill.  I take this to mean that Jack was wounded and was in the hospital.  I wonder if he lived or died?

Thanks for dropping by!  Do come again:)
*** Pamela believes that this says Jack & Sister Margaret..seems to me that could be it!
