The company's analysis would include the slant, flow, pen pressure, letter size, and other characteristics.ĭaniel Kottke, who was a close friend of Steve, provided a number of letters and postcards written by Steve. California-based PSA said that they could do it, but photos wouldn't be sufficient - they would need to carry out a physical examination of both the boards and the handwriting samples.
