1970-80's Vintage Wrigley Field Marathon Oil Chicago Cubs 20" x 16" Poster - this poster would look great framed although it has some creases, minor wear and tear (see photos). Selling as is. Great color! Will ship rolled up and padded in a 17" x 4" x 4" box. Was most likely a promotional item or SGA sponsored by Marathon and offers a great glimpse into what Wrigley Field looked like during the 1970's and 1980's.
