This is the second cave piece created by Edgar Mueller (First piece here). This artistic work was created in Geldern, Germany which is where the previously discussed Lava Burst piece was completed. This was also done for the International Street Painting Competition.
Rain is one of the greatest enemies of street artists. Much effort must be put into precautions against rain or all the difficult labor done will be wasted.
The third of Edgar Mueller's cave project can be found in Ptuj, Slovenia. The mural was completed in four days right in time for the Culture Festival that took place in Ptuj.
A challenge Mueller faced here was the rough surface of the roads. Poor surface condition is a challenge faced by street artists everywhere. This is one reason some street painters prefer doing their work on a canvas to remove any problems with floor conditions.
