Letter from Laura Jackson to J. Howard Woolmer, 1975-04-05

"I note that your estimate includes the carbons. As I have written to you, at some point before the material leaves your hand, it having found, you finding, a purchaser approved by me, and with conditions of handling the material by the purchaser approved by me, I should want the carbons sent to me for examination, in comparison with my xeroxes of the originals."
