Portland Made Humphrey Stickers

We have recently come across a green HHH sticker made in Portland, Oregon. For a long time we had known of the smaller blue HHH sticker. Many members have it in their collections. Both of these stickers have Portland, Oregon union stickers on the face. Pretty neat to find a second sticker.

The two stickers have different photos of HHH in them, but with the same slogan. Note that the different union bugs are position in the same location on each sticker. It makes me wonder why a photo of Humphrey and Muskie were not used on these stickers, even if the stickers mention both candidates.
