Well done ! Yes, there it is )
Now that I know the series (Zenaku ko no Tegashiwa) I should be able to find more. I did find a few more examples but they all seem to have been cut to 9" x 7" (unless they originally printed in this small format) where I have two larger sheets that contain two 9" x 7" picutres on each sheet (seems to be originally published in this format and not stuck together afterwards). Please see extra pics to see what I mean).
Thanks for all your help, I have struggled with kanji books/woodblock books for a while and made no progress, but now feel I am getting somewhere !
Cheers, Anthony
