That doesn't surprise me, someone had to make them. I do though find it rather distasteful people taking pictures at such sites. I've been to Auschwitz too and was shocked at the behaviour of other visitors and how they were having pictures of themselves posing next to various items.
Totally agree with you......some people these days really don't behave with any respect for the meaning of the surroundings they are in
We visited 15 years ago, we were there the day after boxing day, snow and ice -15 C at the time........it really gave you a feel for the appauling conditions those prisoners suffered.
I'm pleased to say that all the visitors with us that day showed total respect and humility for the suffering that occurred there.
I'm afraid to say the selfie trend and social media, crapbook etc has made so many totally vain .....their motivation being a photo on their site which say "oh look at me everyone" ....pathetic IMO.
