color flash-red ink on cream paper. These are the issues of the Boards of Directors
of the Churches of Scientology and are separate and distinct from those HCO Bulletins written by LRH. Only LRH issues may be printed red on white for Technical Bulletins and only LRH issues may have the prefix HCO. These Board issues are valid as tech. The purpose of this distinction is to keep LRH's comm lines pure and to clearly distinguish between Source material and other issues and so that any conflict and/or confusion on Source can easily be resolved.
