Agree with the post above.
To add:
- Title is generalised (doesn't actually state the name of the museum): this creates a sense of personal detachment from the museum which reinforces Skryznecki's apathy towards the place. The could also be double entendre/pun with the reference to 'folk' possibly meaning his ancestors.
- The references to darkness personify it as a pervasive, harmful entity - to use a cliche, his past is coming back to haunt him.
- Skryznecki denies his past, believing it is irrelevant. This is coupled with the fact that the imagery of the museum is particularly tedious and monotonous [e.g. listing of artefacts (box iron, hay knife) bores the responder].
- The motif of colour imagery contrasts the dullness of the museum (grey clay bottle) with the aesthetically pleasing nature of the Autumn street outside (yellow, brown). This works as a form of classic symbolism/juxtaposition of black/white, light/dark, good/evil, life/death etc. The musuem resembles the past, devoid of liveliness and possibly while outdoors beyond the museum portrays the hope of the future.
- The imperfect cadence in the concluding line "Would you please sign the Visitor's Book?" reveals two ideas about Pete's belonging status. (1) Due to immigration he is now a visitor in Poland and Australia - cultural purgatory. (2) The act of signing means he will acknowledge his past, accept his culture and achieve some sense of belonging to a culture.
- The alliteration in the final stanza is that of a soft, consonantal 'w' sound. It is used to reflect Pete's relief in leaving the musuem which implies Pete is moving on from his Polish heritage and looking for new entities to belong.
Far out english is a waste of time. Don't know why I bother.
