tives the counterfeiter simply painted a red opaque substance on one side of the negative over the material he wished to delete. When the negative was printed, the opaquing prevented light from passing through, so that the print showed blanks wherever the negative had been opaqued. However, the original material was still clearly visible on the negative itself.200 In addition, at several points the typed or handwritten material in the Oswald notice had overlapped the printed material. For example, the signature of the official of the local board overlapped the letters "re" in the printed word "President," "l" and a" in the printed word "local," and "viola" in the printed word "violation." When this signature was opaqued out, the portions of the printed material which had been overlapped by the signature were either removed or mutilated. The consequent distortions were ap parent on both the retouched negative and the Hidell notice itself. Similarly, the selective service number typed on the Oswald notice overlapped the margins of the boxes into which it was typed. Although the counterfeiter opaqued out the numerals themselves, the margins of the boxes remained thickened at the points where they had been overlapped by the numerals. These thickened margins were apparent on both the retouched negative and the Hidell notice.201

Reverse side.--The reverse side of the Hidell notice, which was pasted back-to-back to the face, was actually a form of the reverse side of a Selective Service System registration certificate. Essentially, it was counterfeited the same way as the face of the notice: a photograph was made of the reverse side of the Oswald registration certificate, the material which had been typed or stamped on the Oswald registration certificate was opaqued out of the resulting negative, and a photographic print was made from the retouched negative. This is shown by the negative, in which the opaqued-out information is still visible, and by defects in the printed material on the Hidell notice at point where typed-in material had overlapped printed material on the Oswald registration certificate.202

As the final step, new information was typed on the print in the blanks which resulted from the retouching operation.203 Thus "GR" was substituted for "Blue" under color of eyes; "BROWN" was substituted for "Brn" under color of hair; "FAIR" was substituted for "Med." under complexion; "5" [ft.] "9" [in.] was substituted for "5" [ft.] "11" [in.] under height; and "155" was substituted for "150" under weight. The name and address of the local board on the Oswald registration certificate were opaqued out, but substantially the same name and address were typed back onto the Hidell notice.204 As in the signature of the local board official on the face of the notice, a possible reason for deleting the original draft board name and the address and substituting substantially similar material in its place is that if the original material had not been deleted it would have reproduced as a photographic reproduction, which would look much less authentic than typed-in material.205

A limited number of typed uninked indentations are also present. Thus the indented letters "CT" appear before the letter "GR" (under
