Germane to fame A photo of the celebrity in action is preferable. A signed portrait of Lindbergh, for example, is preferable to a signed check, but a signed picture of Lindbergh next to his plane would be ever more desirable. If Lindbergh wrote a letter to his financial backers about this flight, it would be worth more than than correspondence to his mother. Signed jerseys, caps, movie props, clothing or uniforms can be as germane and valuable as any other autographed item. Inscriptions and personalizations This seems to be a matter of personal preference.
Many collectors actually prefer their autographs to be personalized, even if it's to someone else.
Indeed, the autograph guides give the same or similar valuations to a piece regardless of whether or not it is inscribed. Neverthless, these inscribed and personalized items are bought and sold with regularity. Color or Black and white Color is generally preferred in photos, but often black and white is the only thing available, especially on older autographs. Color was available, but generally expensive until the 1960s. Old color often fades, whereas black and white won't, and is usually sharper.
