Mr. Eisenberg. Mr. Cadigan, I hand you an object made of paper, Commission Exhibit 142, also known as Commission Exhibit 626, and ask you if you are familiar with this object?
Mr. Cadigan. Yes; I am.
Mr. Eisenberg. And did you examine this object, this paper bag, to determine its origin, possible origin?
Mr. Cadigan. Yes.
Mr. Eisenberg. Can you tell us how you conducted that examination?
Mr. Cadigan. Yes.
I first saw this paper bag on November 23, 1963, in the FBI laboratory, along with the sample of paper and tape from the Texas School Book Depository obtained November 22, 1963, which is FBI Exhibit D-1.
Mr. Eisenberg. Is that the sample that you are referring to, that you are holding in your hand?
Mr. Cadigan. Yes.
Mr. Eisenberg. And that is marked, as you said, "Paper sample from first floor Texas School Book Depository" and has certain other markings including the words "shipping department"?
