Mr. Eisenberg. Do you believe that was—yes, go ahead.

Mr. Cole. Also on the line reading "From" there is an indentation of another typewriter operation which reads "24 October 1957."

Mr. Eisenberg. Do you believe those indentations were caused by a typewriter set at stencil?

Mr. Cole. Yes; without the interposition of a ribbon between the type bar and the paper.

Mr. Eisenberg. Did you take photographs with side light, as you had in the case of the selective service card, to attempt to bring out these stencil marks?

Mr. Cole. I did.

Mr. Eisenberg. Could you produce those photographs? You are handing me a photograph of the front side of the certificate of service, and is this a photograph which you took?

Mr. Cole. It is.

Mr. Eisenberg. An accurate reproduction of the Exhibit 806?

Mr. Cole. Yes, sir.
