[hatsuto11]

It seems that those are 3 separate phrases, which are not complete...

I would translate them as follows ( I am not sure whether this is correct or not)
花より＝from flowers
ソツアル (卒アル)= classbook, yearbook
or it may also be the abbreviation of 卒業アルバム (meaning school graduation album )
本＝book

ありがとう＝Thanks (thank you)
I actually do not find an obvious relationship between the triple.... They might be some headlines.... or maybe their continuation can be found into the book itself
