Includes clients for which at least one box (usually at least 100 advertisements) have been preserved. A few files contain photocopies or prints made from microfilm, a fact which is noted in the list. Parenthetical identification of the client or product or the JWT office or division responsible for the ad has been added in some cases. The files are arranged alphabetically by client (not product), insofar as it has been possible to determine the client name accurately and as it was known during the relationship with JWT (hence, Lever Brothers in lieu of Unilever). The files are then arranged chronologically within client groupings.
The main clients in this series include Chesebrough Ponds, Eastman Kodak Company, Ford Motor Company, Irving Trust Bank, J.
