This is quite an about face:
Is it appropriate for congregations or individuals to use the logos of legal corporations used by Jehovah’s Witnesses?
A logo is a name, symbol, or trademark designed for easy and definite recognition. The Watch Tower logo is representative of the Watch Tower Bible and Tract Society of Pennsylvania and other corporations used by the organization. The Christian Congregation of Jehovah’s Witnesses uses an open Bible in its letterhead. Other corporations used by Jehovah’s Witnesses have different logos.
Congregations or individuals should not use logos or names of the organization’s legal entities, or variations thereof, on their Kingdom Halls, signs, letterhead, personal objects, and so forth. Such use of the organization’s logos may cause confusion for public officials, publishers, and others about the legal affiliation of the congregation with the organization’s legal entities. Similarly, written correspondence could be misinterpreted as being approved or sent from the world headquarters or the branch office.
The Watch Tower logo, or a variation of it, should not be used in future Kingdom Hall projects even if the Kingdom Hall is owned by a Watch Tower entity. Congregations with existing Kingdom Halls that bear a logo are not required to make immediate changes to signs or designs, since such changes may involve major alterations and much time, effort, and expense. However, consideration should be given to making a change if it would be minor and would not require extensive work. Otherwise it can be made when the building or sign is scheduled for renovation.
