How to start Half a Picture quest?

[AnonymousPony]

In my inventory, I have two pictures with the title "Half a Picture" and are noted as mission items.

One pic is the left half and the other is the right but I can't figure out what to do with them or start the mission. One came from killing the ravenous hunter and the other was from the Brookhaven church.

Any idea what to do with these? It says these are season-exclusive items. I'm playing the Manibus season if that matters.

This isn't the mission where you had to align those two pictures on the side of a building to unlock a door. When I google this question, that mission is what keeps coming up.

Yups, this is indeed very confusing and Google/Bing aren't much help with this mystery either. Those pictures are part of the "The Treasure infinite" world mission which becomes automatically available after you defeated the Treant.

As far as I can tell you completed this mission by finding the 2nd picture in the Brookham church (you got it off Andy) and that completed the mission. But because you never did this for someone else you ended up hanging onto these items.

At least that's my impression.
