Looking for Kelley Purkey National Park Explorers Stamp Set

Hi, I posted this in the FSOT section, but thought I would also post in here too, in case someone wanted to unload it or knew where one could find older (I think this was 2019) KP stamp sets. I have tried ebay and mercari. 

This is the only link I could find, it is down a bit, the one with the buffalo badge. Thanks!!
