Secret room bonus content

I am stuck on the first part of the secret room under the bonus content. Where to put the portrait...

Tap on top of the secret room screen and a portrait tree will open up. Then u match the portrait with it's outline.

I'm in the secret room, Main Hall. There's an axe stuck in the card slot and I can't get it to move. There's a flower shape on the axe blade, but I'm not finding a flower anywhere. How do I move the axe?
