I have a bit of a hodgepodge of cards today, as these are from a variety of swaps on the Postcrossing forum.
I thought this one was quite striking and with such vivid colors. The back caption reads;
Lightning strikes over Uluru.
This is a sandstone rock (Ayers Rock) formation located in the southern part of the Northern Territory in Australia. As it turns out Uluru-Kata Tjuta National Park is on the UNESCO World Heritage List, so I've received my first card without even trying.
This is a curious card. I only know it is from a Russian book. Unfortunately I don't know the name of the author or the title. Perhaps if someone happens by who can read Cyrillic they can help me out? I'm guessing it is a children's book.
Mystery solved: Thanks to Leo for confirming that this is indeed the cover of a (famous) children's book: Alice in Wonderland by Lewis Carroll.
Another card from Russia came just a week too late for Valentine's Day. The sender tells me that the words on the front read "With Love". Very sweet card.
And the last card is a steam locomotive from Taiwan. The sender says this now only runs on the forest railway.
