While these are cute, I sure hope you clean up after yourself.

while these are cute it's still vandalism and make some people clean after you

The cleaners must love you.

OK people are going to come for me with this comment, but honestly as much as I appreciate your creativity, this is an act of vandalism. -_-

Vandalism done.... right? I don't how how I feel about this.

Vandalism? Maybe. But maybe some haven't heard of a dry wipe marker pen? Not saying it is "right" but it isn't permanent and even if it isn't a dry wipe pen it wouldn't be that difficult to clean it off glass. I think it is okay as long they clean it off again.

It might looks fun and cute, but it's very inconsiderate for the people who have to clean it. The airplane turn time is very serious and need to be fast. Now, cause of your idiots think is cool, they have to do extra time to clean your mess.

This is hilarious. I love it!

It looks like dry erase marker.

You're welcome STP! STP means please in french as S'il Te Plait. I think it will be helpful to know that if you ever take a french plane when they will kick you out^^ just said that you asked by STP writing, try it...

Was this in dry erase marker or a permanent marker?

Are these dry erase markers? Because I'm going to do this with dry erase markers

His art makes me smile. For me it's ok if it's easily washable. I say this as a cleaning lady.

Ok guys. Get this, and brace yourself because this may come as a little shock. THIS IS DRY ERASE MARKER :0 D. R. Y. E.R.A.S.E M.A.R.K.E.R Not sharpie or anything. It can EASILY but wiped off. So how exactly is it vandalism and how exactly is it a struggle to clean up. Come-on people, at least have some knowledge before commenting.
