In regard to listing the cast of characters responsible for the praise and or
blame for how an exhibition turned out, here are a couple more thoughts.
   A credit panel at the Adler Planetarium in Chicago lists and thanks, among
others, the visitors who participated in the formative evaluation of exhibit
mock-ups during the development phase.
   The public TV station in Chicago WTTW made a film about the real nitty
gritty of making of the "Africa" exhibition at the Field Museum of Natural
History.  The video was much more than just a fluffy piece of promotion.
   The longest, most complete (and interpretive) credit panel I've  ever seen
was at the Dickson Mounds Museum (Illinois) that listed the different
consultants in detail who helped with dioramas, models and mounts, audio,
video, research, writing, design, etc., etc..  It was more than just a list
of names.  It really communicated the breath and diversity of the skills
involved.

These three examples have more to do with letting visitors know who and what
different kinds of skills it takes to make a whole exhibition, more than a
single explanation of a technique like taxidermy (examples at Field Museum
and many other places), kimono dyeing (in the current excellent show at the
National Museum of Natural History, mentioned in regard to this topic), or
exciting but limited audiences for educational programs (such as mentioned by
KBaker earlier).
