bookbndrbob..Thanks for the comment which made me search further...Thanks buddy.
It is difficult to prove/disprove if it is an authentic signature or not...Here is what my analysis came up with.
Under magnification there are dots usually not associated with standard ink pad and stamp...see below.

Next is a close up of part of the signature which shows irregular line width which may indicate pen/marker pressure as shown below..

Now here is the stickler that made me believe the signature was hand written...Thee is an overlap on the signature which will cause a darkening of the ink/pen/marker colour...see below.


CONCLUSION: I would say it probably was hand written by the president...Next question, did he on this 50th anniversary sign 10. 100. 1000. 10,000...Not likley any more than 100..
