Which rare books or poems u own?

For me, it is the English translation of Howling at the moon by Hagiwara Sakutarō , it is a book full of poems by the great poet Hagiwara Sakutarō, it is rare as in I have gone to Hell and Heaven to find the book (Even at that time of searching, Amazon did not have it, I do not know if Amazon has it now). The poems in these are free verse, that try to etch raw emotions at human psyche and if u are lucky! U will get some really artistic drawings in the book. The title may seem unnecessary at first like why howling at moon? But after giving it enough read u will know why! So I am not giving any spoilers, I let u explore it urself.

Do share urs too, would be glad to hear new recommendations.
