Rev. Billy Graham's doctors say he is showing signs of improvement after recuperating for several days in a North Carolina hospital.
    
The 93-year-old evangelist was hospitalized Nov. 30 for pneumonia
    
Officials at Mission Hospital in Asheville, N.C., say Graham is progressing well with physical therapy and taking walks along the hospital's corridor.

The evangelist's most recent book, Nearing Home, was published last month.

The Billy Graham Evangelistic Association said Graham was also starting work on a new project that reaffirms "the evangelistic message he has preached for more than 60 years."

Doctors haven't set a date for his discharge.
