Result of examination:
It was concluded that the hand printing on Q35 and Q29 was prepared by one person. It was not definitely determined whether the hand printing on Q31 was prepared by the person preparing Q35 and Q29 because of variations in the limited comparable material; however, characteristics were noted which indicate that Q31 was probably prepared by the person who prepared Q35 and Q29.
The typewriting on Q36 is the same style as the typewriting on Q30, but it was not determined whether these specimens were prepared on the same typewriter because of the lack of significant defects.
No watermarks; indented writing or other features were found on Q35 and Q36 which would be of value in determining the source of these specimens.
Q35 and Q36 were photographed and will be returned separately.
