The last major Transformers-related item uncovered from the storage of former Sunbow producer Flint Dille back in 2020 is now available online. Flint's character binder, which received its last update on December 3rd, 1986. Nearly all of the 1987 toy lineup is represented within its 333 pages, as well as a copy of Bob Budiansky's treatment for the Marvel Comics' Headmasters miniseries.
Due to its size at 333 pages, the binder has been split up into three galleries, which can be viewed at the Sunbow Marvel Archive: Briefing/Reference Binder galleries
