Dwight D. Eisenhower's personally-owned personalized golf ball, stamped on the side in black, "Mr. President," and marked "US, Royal Special, 4," sealed in its original packaging. Also includes a bold fountain pen signature as president, "Dwight D. Eisenhower," on a pale green 4.5 x 1.25 slip torn from a sheet of White House stationery. In fine condition. Eisenhower enjoyed a passion for golf, joining the Augusta National Golf Club upon his return from Europe and installing a putting green on the White House lawn during his presidency. An avid golfer both during and after his administration, Eisenhower was inducted into the World Golf Hall of Fame in 2009. From the collection of Brigadier General Robert L. Schulz, longtime military aide to Dwight D. Eisenhower.
