There are the legendary, epic poems, which the elves adore writing and reading. On the other end of the scale are the limericks, the ruder the better, which the sprite communities (imps and pixies) write and publicize as much as possible. Limericks do appear on most but definitely not all public walls (you'd have to be brave or an idiot to put them on the Queen's Palace walls or the home of the Chief Witch to name two exemptions).
The elves despair because their work doesn't get nearly so much exposure and they feel their sagas in poetic form deserve publicity. They also don't like limericks thinking them to be coarse (completely missing the point of them of course).
The Fairy News Network does have an arts magazine programme called Airy-Fairy Art, which makes true lovers of art, including the Queen, despair but it does give reasonable coverage of literature, ignores limericks, and shows exhibitions of landscapes so the monarch forgives it for its rotten title. The elves tend to do the same. Naturally the sprites don't tune into this (they have protested limericks are an art form but given there's no danger of the humorous five line verse dying out, they are unlikely to ever get on to this show).
Eileen likes both forms of poetry and thinks there is plenty of room for both but she was a lone voice in the Kingdom over this. Folk tended to fall into either camp and stay there.
