The signs said things like "Rosalynn Carter, if my daughter is ever drafted it will be your fault!" and "Mrs. Carter, you have no right to lobby ERA!"

A group estimated at 150 persons - mostly women - carried the placards yesterday in front of the White House to protest the First Lady's involvement in efforts to pass the Equal Rights Amendment, would prohibit descrimination on the basis of sex.

Phyllis Schlafly, national chairman of Stop ERA and leader of the demonstration, charged that Mrs. Carter's use of White House pressure to help get ERA ratified "violates Article V of the U.S. Constitution."

"That article gives ratification power to Congress and to the state legislature," Mrs. Schlafly said. "State legislators across the country resent this improper White House pressure."

Mrs. Carter declined comment on Mrs. Schafly protest but, according to her press secretary, "she will continue to work in support of ERA."

Following a precedent set by former First Lady Betty Ford, Mrs. Carter had called legislators in Indiana and Virginia in recent weeks to urge ratification of ERA.

The amendment was ratified by Indiana, but passage failed in Virginia by one vote. Three more states must ratify the proposal by March 22, 1979, to make it part of the U.S. Constitution.

Among the demonstrators yesterday was 76-year-old Hilda Griffith of Arlington, who said she had marched as one of the "original suffragettes" when she was 15 years old. Now, she said, "we should quit while we're ahead. We've got equal pay for equal work and that's enough!"
