Leading wire to wire, the Asahel Curtis glass photographic negatives of Grand Coulee Dam was the overwhelming winner in April’s State Library jewels online poll.

The Curtis negatives took first with 62 percent, well ahead of the Seattle World’s Fair Commission records (31 percent) and W.E. McCroskey’s poem about Northwest Pioneers (7 percent). The image above is one of the few color negatives in that collection. The black-and-white negatives feature the dam’s construction.

Next week we’ll begin a blog series about May’s Archives treasures, so be sure to watch for that and choose your favorite out of the three items featured.
