Most Subterranean Facility — Stamp Fulfillment Services, located in Kansas City, MO, is located in a limestone cave 150 feet under-ground. It is the Postal Service’s only facility located in such an under-ground environment. The consistent, year-round temperatures and humidity levels in the caves allow the stamps to be maintained in mint-quality condition. The underground facility also keeps the inventory and employees safe from snow, flooding, winds and tornadic activity common in the Midwest.
here is the envelope that is the [most viewed] of all the envelopes on my blog. there are a ton of stats when you go to the inner sanctum of the blog.
i can't imagine why this is such a popular envelope. i see it on Pinterest all the time. it's cute. but i wouldn't exactly call it brilliant. drawing white lines across darker strokes is still one of my go-to techniques.
