Former postmaster general Benjamin F. Bailar has resigned from the Citizens’ Stamp Advisory Committee, questioning the value of continuing a panel that has guided United States stamp policy since 1957.

In a letter to Postmaster General Patrick R. Donahoe, Bailar suggested that the committee has become overly concerned about trying to raise money for the cash-poor U.S. Postal Service and less worried about what message U.S. stamps offer the world.

His July 23 letter was not meant to be made public but Linn’s obtained a copy from a source outside the Postal Service.

Bailar’s nine-paragraph letter indicates that concerns raised by CSAC at a September 2013 meeting, when all members signed a letter of protest to Donahoe about their role in the stamp program, have not been resolved.
