The Combine Honnete Ober Advancer Mercantiles or CHOAM controls all economic affairs across the cosmos, although it relies upon the Spacing Guild for transport across space due to the Guild's monopoly on faster-than-light travel. CHOAM touched almost all products the Guild will transport, from art forms to technology and of course melange. Many Houses depend on CHOAM profits, and an enormous proportion of those depend on melange. Of course if you're interested in this shirt, you probably knew all that already as you've read Dune. This original CHOAM design includes some light vintage wear to give it a little authenticity and galactic cred.
