Forger Hunter R. Hickey (Kevin McCarthy) has a small boy ask McGarrett to autograph his picture on a magazine cover to get a sample for forgery. The signature as McGarrett is writing it on the cover, however, is quite different from the version shown later when Hickey tries to copy it - for example, the "G" in "McGarrett" is written on his left shoulder as he is shown writing it, whereas the later version has his entire signature fitting neatly within the lighter area of his suit, and the ink on the later version of the signature is also much darker.
