Dimensions: 12 × 23 7/8 in. (30.5 × 60.6 cm)

Copy of pages 12-13 for an electroencephalograph (EEG) test performed on Jack Ruby by EEG Laboratory in Dallas, Texas on January 28, 1964.

The pages are printed on a long, narrow sheet of thick paper. The test shows eight parallel jagged lines that run horizontally across the paper. At the top middle and far right of the page are the page numbers "012" and "013" respectively. The last line of the EEG reading between the page numbers has a place where the line has more exaggerated peaks and valleys; this small portion has been underlined.

This object was originally part of the evidence collected by the Dallas County District Attorney’s Office and specifically prosecutors Henry Wade and Bill Alexander during the investigation leading up to the Jack Ruby trial for the murder of Lee Harvey Oswald.
