i use regular paper when i send, its a lot cheaper then photo paper and i personally like how my printer prints.
also if you frame your autographs like me then once they are in a frame its not that much of a difference.
celebrities have there own promo photo as well so what i do is ill send my own printed out photo and then ask if they can send one of there photos as well(these photo's are almost always on photo paper)

ps.if you do frame your autographs do not put them in direct sunlight it will ruin the photo with time.

hope i was helpful and happy collecting.

Sure you can print the photo on regular paper, but I would suggest going with cardstock material, it's a bit thicker than regualr printer paper and not so flimsy.

If I am sending a letter and asking for an autograph, does the picture I plan on sending have to be a hard copy?
Or can it be printed on regular white printer paper?

Please and thank you!
