When a colleague returned from a conference in Hawaii (back in 2019), he excitedly showed me a poster designed for another observatory – done in a style reminiscent of the WPA-produced National Park posters. I was familiar with both the style and the poster in question and had been working on a few WPA-inspired versions for our own observatory as a side project. With the added interest from my colleague, I stepped up my efforts, producing two poster designs in quick succession (and plans to produce more).
The design for the Green Bank Telescope was completed first, but work had been started on the design for the 140-foot Telescope back in 2018.
