And I believe we cannot put the Church logo at these business cads.
When I'm a missionary, I can remember some Church employees and senior missionaries at Brazilian Church Offices in São Paulo uses a business card with a light blue Church logo in the left part of the card and all other informations in a black standard font in the right part of the site (the name, the calling, the unit address or personal address, email and phone).
Since stationary is available in USA by Distribution Services, I immagined it can be made easy available to Church general and area autorities, but I don't believe it's available to bishops and stake presidents, for exemple. In "international areas" (outside USA and Canada), any stationary (including letterheads and envelopes) are available from the Church, and leaders need to create it using commercial companies or personal computers to do that.
