Kirkland Sobremesa is mentioned on the page of new Sunbeam Borg Ruiz!! Fulltext of Bo's page can be found here but the relevant section is as follows:
"Most recently Ruiz has obtained a set of enchanted postcards from Kirkland Sobremesa. The cards were delivered via the landline telephone that is installed in the home's single bathroom. These postcards depict various locations around Yellowstone, and are infused with the power of Sun .1, giving them the ability to transport the owner to the location depicted. Ruiz currently keeps these cards divided between multiple decks, and only accidentally visits the Park(Park) through them on occasion."
