Notice that the ad just listed the players' names, with no preview of what the pictures looked like. Jewel put me out of the coloring the ad business.
On August 9th the Cubs lost a heart breaker to the Expos in 10 innings, 1-0. It was their first loss in a week, having won their previous six games. They were on a roll. Despite the loss, the lead over the Mets was still 4½ games. All four of the Jewel players were major contributors to the teams success.
Bobby Dernier was the leadoff hitter and half of the "Daily Double" with Ryne Sandberg. He came to the Cubs from the Phillies at the end of spring training. The picture seems to have some serious cropping issues. There's way too much blank space above his head. They should have cropped tighter and eliminated the empty space.
The Cubs added Dennis Eckersley in late May, sending Bill Bucker to the Red Sox. They needed more starting pitching and Buckner was expendable.
Larry Bowa was the team's shortstop. He was past his prime, but still provided an occasional spark.
Steve Trout worked his way up to the team's #2 starter and had the best season of his career.
