Let's say that the Pawnshop is in play and some characters have been there and sold some items already. There is for example a purchase deck sword on the Pawnshop as well as an Emerald from the Highlands and a Wanted Poster. Do I shuffle those cards with the other City-street cards and place them on top of the Adventure deck, or do I discard them?
The Pawhshop, but also the Pantheon and Wanted List, or the Lake of Visions on the main board, have some other cards on them. Usually these cards say that they do not count towards the number of cards on the space. This means that those cards are tied to the card and not to the space.
If those Places are discarded, or affected by Travelling Bazaar, the cards on them must be destined to the appropriate discard pile. I will do the same for the Items on the Pawnshop, as they are bond to the Pawnshop card and can't be "separated" and shuffled with other cards.
It feels a bit odd to draw a Wanted Poster from the Adventure deck…
I don't think Wanted Posters have to be included, but you're right if you say that there's no indication about them.
