Both the Hen Fetch prop AND the effect share the name "Mental Epic." I believe that Fetch based his creation on Peter Warlock's earlier effect called "The Taped Slate."
"Confabulation" is the name of the effect involving multiple related predictions created by Alan Shaxton and popularized by, among others, Ron Wilson "The Uncanny Scot." In several versions (e.g., Wilson's and others) the prediction is found in a sealed envelope which, in turn, is found inside the zipped compartment of a wallet. A variety of wallets (the LePaul, Mullica, Seabrooke and others) have been used, with the LePaul (Wilson's preference) being one of the most popular.
Sounds like you're spending too much time on the Internet instead of studying magic and practicing your penmanship.
(Sorry, I just couldn't resist the temptation)
