The book are about foreign countries and foreign goods.
The writer of these books is a buyer of sundries goods.
So there are a lot of sundries in them.
When I was a high school student, I found these in a local library.
And I was so excited because I could see lots of unfamiliar and attractive goods.
I'd not known Parc G醇・ll (Park Guell) in Spain until I found it in these books.
It's so colorful that I can enjoy just seeing these.
I can meet lots of foreign cultures, handiworks and trivial goods.
With these books, I feel like going abroad and meeting some uncharted world!
