Gary Savage, "JFK First Day Evidence", p. 108
"He told Rusty and me that he could tell it wasn't put on there recently by the way it took the fingerprint powder. He said what makes a print of this sort is a lack of moisture, and this print had dried out. He said he took a small camel hair brush and dipped it in fingerprint powder and lightly brushed it. He then placed a strip of 2" scotch tape over the developed print and rubbed it down before finally lifting the tape containing the print off and placed it on a card. He said he then compared the lift to Oswald's palm print card and was certain that it was Oswald's. He also said that after the lift, he could still see an impression of the palm print left on the barrel."
