I am really excited about this new Minifigure Collection. Thank you to the LEGO employees who made this happen! I will be purchasing multiple copies of volume four.
The Classic-Castle figure was in set 0016 ( http://www.classic-castle.com/sets/archives/0016.html
). However, this set was released in 1979 and not 1978. Of all previous minifigure collection figures, this knight is the most valuable (at least $12 USD used). The bley flared helm has been sold on bricklink (via LEGOLAND theme park surplus) but this is the first time it has been in a set.
I am also excited to see the Blacktron 1 figure for the space fans. Santa is a bit of a common figure, but many people will like him as well.
I find it interesting that one of the most common forestman torsos was chosen. Still, it is great to see this figure, the forestman cap for the first time since 1997, and the small plume for the first time since 2003's last castle accessory pack ( http://www.classic-castle.com/sets/archives/10066.html
). The use of this plume brings up more questions. Are old plumes back? Did TLG have a surplus of red plumes to use in these sets? Hopefully plumes will return in a variety of sizes and colors.
