What does the scan show?
A person reads every report. Corrections are made by hand, to the data — titles, dates, names, which pages belong together — never to the scans, and they can take a while to appear.

No indented writing, watermarks or other features were found on Q1 through Q4 which would be of value in determining the source of these specimens. It is noted that indented impressions of the Q1 address appear on Q2.
The printed cutout words of Q2 were compared with the K1 newspaper. Printing characteristics indicate that the cutout words on Q2, with the exception of the "ity" portion of "Hospitality," came from K1, or an earlier edition of this paper with the same type setup for these words.
Q1 through Q4 were photographed and will be returned separately. K1 is being returned to Sacramento with copies of this report.
