1970's Levis 505

This was my first vintage jean. Bought at 2nd-Boom in Ebisu Tokyo.   A great vintage & secondhand clothes shop. Even compared to NYC, Tokyo is vintage-shop heaven. Although the price is higher than   in NYC, things are well curated and selected. Anyway, this pair, 70's 505 with a great faded indigo blue. It was 29,000 yen (almost USD300). I know it is not cheap, but not extremely expensive considering the fact that the high end denim brands offer similar price for artificially processed jeans. This one has been through a real aging process and it is romantic. Thoughts?
