An oil portrait of Jesus Christ bearing what turned out to be a rare autograph of the Son of God was purchased for $65 at an estate sale last weekend, religious relic experts said Tuesday. 'Careful examination of the signature's authentic Aramaic cursive loop on the 'J' and 'C,' plus the distinctive early-A.D. touch of underlining the name and adding a couple of jaunty diagonal dashes, confirms that it is indeed genuine,' collectibles appraiser Mike Shankman told reporters, describing the signed message that reads 'Gary, best of luck!' 'These are actually a lot rarer than you'd think. What a great find.' As of press time, one Greek Orthodox antiquarian had offered a conflicting appraisal, saying that while the signature was definitely that of Christ, the Savior may have been amusing Himself by autographing a painting of singer/ actor Kris Kristofferson.
