If you want an autograph but can't see them anymore on the tour, You still can send them a mail via post to:
Lordi c/o Sony Music Finland
Tallberginkatu 2 A 5
00180 Helsinki
Finland
When you want to send a mail to one member specifically, you can mark the envelope with the band member's name.
Maybe ad international reply coupons to your mail so they don't have to pay the postage.
Be sure to have a lot of patience since the band is very busy. I'm sure they will replay, but I can't tell you when.
