.. What should I do after Gunnar is kicked out?

At some point after you do the puzzle in the town's crow's nest --

What am I doing in the crow's nest in the middle of town?

-- you'll return to the Missti Skip to see Gunnar being tossed out. Not too surprising, once you talk to Elisabet and find out why.

Not long after, you return to the Missti Skip to find Gunnar standing in the lobby looking ill at ease. Talk to him to find --

-- that he left a box of his personal stuff in the bar, and he wants you to get it. Look in his usual spot (and now is a good time to grab that coaster and read the letters here too) behind the giant wheel on the wall.

Nancy opens the box without asking you, but go ahead and see what's in there; Gunnar doesn't mind. He doesn't seem quite so obnoxious now, does he? Poor guy.

After you return his box, head upstairs to sleep. When you come back downstairs, Gunnar is back in his spot and has the thing he promised you --

-- another set of flower sketches.

How do I solve the flower picture inside the footlocker lid?
