On a trip to Baku, Azerbaijan 5 years or so ago, I took a number of photos of sculptures and things that caught my eye around town. For the most part all these years later I have no idea who or what they are. I learned my lesson on some later trips. In Sofia and Zagreb, for instance, I wrote things down at night in the hotel room. I'm not sure I had a good enough guide book or other information handy in Baku. It was still the early days of my digital camera too.
Hah! I know one, Haydar Aliyev, according to wikipedia, the 3rd President of Azerbaijan
