Unfortunately for JayHawk, this "Mayonnaise & Bread" really had little to do with mayo (or bread for that matter). It is really just a name for a web site, which is described as "a cluster bomb of art sauce and randomness which may truly stimulate and tickle that sticky and gooey part of your brain where one's fancies lay quivering in the darkness of your skull". That's a mouthful (pun intended).
Mayonnaise & Bread advertises that they do fully commissioned art. From my scanning of the site, they appear to do outstanding work and have done so for many well-known companies. Check out mayonnaiseandbread.com to see for yourself.
Getting back to our friend JayHawk, it took him several days to recover from his disappointment (no offense to the M&B folks). JayHawk was hoping for a comic book series focused on mayo. Perhaps even may o samples. So this year at Wizard World, I will be a great friend and keep him away from their booth, lest he relive the experience.
