Brown paper bag

-On Dec 20th I bought a sandwich from Cozy Soup & Burger (on Broadway at Astor Place, in Manhattan), and received it in a Duro brown bag by Blanca Guillen, and had the code above. Another well-made bag that will be reused.

I performed a web search for that name, and happened upon a blog post that mentioned this and other names on paper bags. And to another site that seems to keep a log of these bags, but doesn’t explain why (other than to state that they are not affiliated with Duro bag makers.)

I imagine a documentary film on this subject.
