Have you designed a stamp before? What unique challenges did it present?  

I have never designed a stamp before, It was a really fun challenge of thinking small. The amount of detail in traditional stamps is really high, essentially you get to design a very small poster. The challenge of knowing the right amount of detail to add coupled with a unique aspect ratio made this design a little bit more challenging then normal. From a printing standpoint, this is about the smallest that can be reliably silkscreened. Originally my image was a flood of color with the ranger station knocked out, but I was worried that they would fill in when I did the silkscreen printing. Even then, I had some trouble with the slightest lines.


What was the most interesting or fun aspect of designing a poster stamp?

I really liked the paper, it had a wonder tactile quality and was fun work with. I also liked the framing and puzzle aspect of creating the imagery at that scale.


Tell us about the art. Did you create something new for this stamp?  

I repurposed an existing digital illustration that I create in procreate, I had to do some fine tuning to make sure my details could come through, and I had to vectorize the imagery to make sure that I could get a high quality burn for the silkscreen process.


Anything else?   

Each stamp was made with love!
