Description of the flag

I have searched for a digital image of our flag and one is not available. We do have a flag and it is the county seal on a yellow background.

The Hillsborough County flag was first hoisted on 11 January 1971 at the county courthouse. It depicts on a yellow field the county seal adopted after a contest for its 200th anniversary (the article from the same year says it was in 1989 but the actual anniversary was in 1969), being designed by William Wagner Jr. of Manchester; information based on newspaper records of the time from the Nashua Telegraph.

The county seal depicts is circular, having a white outer ring bordered in yellow and black. The ring reads the legend HILLSBOROUGH COUNTY and NEW HAMPSHIRE, divided by stars. The inner ring's lower half depicts 31 white stars over a blue field, signifying its number of towns and cities and also referencing the American flag. The upper half is divided into three triangles; the ones to the side in blue and the central one in white. The left triangle depicts a corn plant for agriculture as a historically important source; the right triangle the Monadnock Mountains with a stream flowing by them for its nature; and finally, a regulator in the center with a gear descending entirely in yellow and black outlines, signifying industry. The wheel depicts in its center the image on the New Hampshire State Seal, and the year of its establishment in 1769 underneath it in its outer ring.
