Now, all of these things on the charts Exhibit A, B, and C

Mr. Eisenberg. I don't think you need to point to them in detail, since you have already pointed to those items.

Mr. Cole. Yes.

I also find a substantial agreement in details of the signature, "Lee H. Oswald," as shown by the photograph 794, and signatures shown in the standard writing, with particular regard to the signature of chart C, item 6, next to the last line.

This constitutes my reasons for believing that the writing on Commission Exhibit 793 is in the hand of the person who made the standard writing.

Mr. Eisenberg. Mr. Cole, there seems to be a double line in several of these letters on the reverse side of this change-of-address card, such as the "D" in "DALLAS," the "e" in "Texas" and so forth. Can you give any explanation for that?

Mr. Cole. Well, I think the double line is more evident in the address "4907 Magazine Street, New Orleans, La."

Mr. Eisenberg. Yes?

Mr. Cole. And a possible reason is that the writer was dissatisfied with the width of the line as shown on the two lines above. While I regard it as having a fair legibility, the only explanation I can see is that for this particular document the writer wanted a heavier writing and, of course, one way to get it is to go over it again.

A thing of this kind can also be related to a writer's knowledge of the functioning of a certain pen.
