Vasa Croe found a significant piece of text from the Smidgens comic strip, reading "The pace isn't any slower! In fact it's just one big sprawling subdivided rat race". The particular example below (found by David Oranchak) is from the Oakland Tribune on September 25th 1970. The Zodiac Killer took eleven consecutive words from this comic strip.
THE "PACE" POSTCARD AUTHENTIC
Thanks to Jibberjabber for his diligent work in this matter. Cragle, another contributor to the Tapatalk forum, has previously found the same and similar newspaper cuttings related to the 13-Hole postcard. I appreciate their efforts to establish a greater understanding of the Zodiac Killer.
