Mr. Cole. Yes, sir.

Mr. Eisenberg. Does handwriting change over the course of time, Mr. Cole?

Mr. Cole. Handwriting does change over the course of time, but usually fairly large periods are involved, 5 or 10 years or such.

Mr. Eisenberg. Is there any variation in the writing instruments which were used to produce the various standards?

Mr. Cole. Yes; I think a variety of instruments were used.

Mr. Eisenberg. Does this affect your ability to use the standards as against the questioned documents or as against those questioned documents produced with other writing instruments?

Mr. Cole. It does not adversely affect my ability to make a comparison.

Mr. Eisenberg. That is, you are able to compare a document produced by a ballpoint pen with a document produced by a fountain pen and vice versa?

Mr. Cole. Yes, sir.

Mr. Eisenberg. Do the standards show both cursive writing and handprinting?
