Traditionally the author of a book would sign the book on the inside using an ink pen. If the signature you are getting is of a sports personality the autograph would be worth more on the cover as it would make for a better display.
The better the signature displays the more valuable. You should use an ink, and color that would stand out in contrast with the cover of the book such as a Sharpie. Be sure to allow the ink to fully dry before covering it with any protective covering to avoid smearing.
Regardless where you decide to have the book signed, it is nice to have it personalized for example: "To John Best Wishes..." but keep in mind that if you ever decide to sell the autographed book it will have a lower value unless you sell it to someone named John.
Sharpie would be most preferred on a photo as the signature will stand out more. A pen signed photo would not stand out as well, and could also "indent" the signature into the photo. When having a photo signed in sharpie be sure to allow the ink to fully dry before handling, and placing in a protective plastic. If the ink is not completely dry the ink will smear. If the sharpie signed photograph is kept in a plastic protector, keep in mind that if the conditions are not right the signature could sweet onto the plastic. In the case of a Baseball a blue ballpoint pen (Bic) would be most preferred, and recommended over a sharpie. Sharpie is not used for signing baseballs because of the porous properties of the baseball will absorb the ink and the signature will tend to bleed into the cover of the ball.
The Ideal conditions for display would be indirect lighting, at a room temperature of 65 - 70 degrees, and 50% humidity. Always check your signatures periodically for signs of fading or deterioration, and avoid excessive handling.
You might want to visit an art supply store and look into having the "canvas print" sealed before having it signed. I know of a spray that is sold for protecting and preserving artwork like pastels, and chalk. Let them know your intentions, and they should be able to recommend something, so that the signature does not seep into the print over time.
[EDIT by NOTUS.zip: A Paint Pen should work even better, although ultra fine Sharpie paint pens are notoriously unreliable, anything with a larger tip than ultra fine should suffice. I sign all my paintings with paint pens and use pastels to write the name on the back.]
A thin point sharpie is the best pen to use when autographing a hockey card.
Sharpies usually work pretty well.
A Sharpy fine point marker is good. It does not erase easily.
I would use a fine tip, regular run of the mill, Sharpie. The ultra fine tip would be too small and not hold up as long.
You get fraus teeth and ring the phone then get the pen and go to zac and say I want your autograph
A ballpoint pen of some sort is generally good.
Autograph values depend on many factors. These include what type of item is signed, the type of pen/ink used, if the player is alive or deceased etc. Brooks was a frequent signed throughout his career. A signed baseball card may be worth about $2-3, a ball might get $10-15, and a photo $5-10.
If it is a glossy helmet, you can probably use a Q tip or cotton swab dipped in rubbing alcohol. Just rub the autograph and it will come off.
The best thing you can do to get a new cartridge type fountain pen to work is by replacing the cartridge. They are known for drying out when stored which makes it impossible for them to function properly.
