Best pen for autograph- card

[Mozzie22]

If this has been covered a hundred times I apologize but I'm thinking about getting a couple old Topps cards signed and was wondering which pen is the best. I see cards signed in a very thin line and tend to like those the best. I'd love some opinions with scans of signed cards if you guys have them. Thanks.

I go with the trusty blue Sharpie though the pen you may want is the Staedtler Lumocolor pen.

Staedtler Lumocolor Fine Tip Permanent is what the card companies use.
