For years Steve Frykholm, the in-house graphic designer for Herman Miller created posters for their annual summer employee picnic. This example from 1979 typifies his bold graphic style focusing on colorful close-ups of picnic food and fun– in this case, chicken on the grill.
 
In very good original condition, the poster has been professionally framed. 
 
Overall it measures: 39.75" X 25.25"w X .75"
