Childhood memory

While my next brainy post is baking, let me share with you a picture from my childhood.

I took this photo just today in the morning on my way to the office. The thing is that in 2026 in the Yerevan metro you can see exactly the same metal plates and signage I saw in 1989 in Moscow. Probably, this metro car was built 37 years ago at the Mytishchi Metro Car Factory and has been in use in the Yerevan metro ever since.
