Best kept secret

Funny story, sorta. The self-design Liberal Arts major which I direct is introducing its first dedicated course, modeled on something in the far larger Bachelors Program for Adult and Transfer Students self-design program with which we currently merging. Deans have long hoped more of our students would choose this path, but many apparently don't even know it exists! So we had a talented student designer come up with this poster for us. ("Best kept secret" was my idea.) Student workers are the best! Except when they're not. The student charged with reproducing and posting them claims to have put them up but there are none to be seen. The secret remains secret.
