It's a little late but I thought I should share pics of the Birthday wedding limited eds and the bonus items they come with.
I bought Limited Types A, B and C. Each copy came with a free Birthday wedding promo poster. Sadly, HMV folds their posters for shipping, hence the ugly creases.

Back of the CDs (nice pics of Yukirin there)
Closer look at the luxurious metallic finish of the lyrics booklet
