Taken from S48:
"B.L.T. stands for Beautiful Lady & Television. They collaborate with AKB48 in magazines such as the original B.L.T., B.L.T. U-17, and the special AKBxB.L.T. issues. From the AKBxB.L.T. issues which can only be purchased at the theatre or bought online, are collectible photos. It usually comes in four versions, and are sold at different times. One issue at the beginning of the week, second issue during second week, and the rest on the web. The B.L.T. photos that come with it follow the weeks respectively, 1st week - A, 2nd week - B and also C (which can only be ordered through the web)"
1. It's kinda rare / difficult to get
2. It's signed!
3. The value (of any collector item basically) is completely irrational
I wouldn't pay more than 3 euro or something for this, while it could mean the world to some fan.
There also other pictures called "gachas"
"Gacha are balls that are sold at the theatre towards the end of the month. They are sold for 300 yen each and contain random prizes and points. Random prizes can include member events, vacation trips, gaming consoles, and more. The points can be used at the theatre in exchange for items such as 2-shots and member photos. There is no limit to how many you can buy so you could buy two bags full of gachas if you wanted to."
But they abandoned this system in July (?) this year and replaced it with a totally new system. In the new system you buy a card pack (from your preferred team) for 1000y, which contains 5 pictures at random. Someone correct me of I'm wrong here..
Maybe we could use a collectors / stuff you want thread?
