Problems 1: vandalism

Outdoor interpretation has many problems. Here are some examples of vandalism:

A small amount of damage can totally ruin the panel:
(Křívoklátsko Protected Landscape Area, Czech Republic)

Tougher material is more resistant - lots of scratches made here but it is still legible:
(Dovedale, UK)

Graffiti is a common problem, especially in urban areas:
(Prague, Czech Republic)

Broken, but still there:
(Lueneberge Heide, Germany)

Lightweight material, easy to break:

But even if it is stronger, a determined vandal will succeed!:

Beautiful interpretation

Interpretation panels have to be effective, but sometimes a little extra style or imagination is welcome!

Beautiful engraving around this sign at Moor Copse Nature Reserve, UK:

Animal tracks engraved on this one at Ashtead Common, UK:

Something a bit different to describe peat extraction at Pietzmoor, Lueneberger Heide, Germany:

Great way of displaying photos at Točník castle, Czech Republic:

Appropriate memorial for a local geologist, near Brno, Czech Republic:

Clever way of visualisation, Caruntum, Austria:

Please let me know what you think of them and if you know of any other stylish or imaginative interpretation.
