Hello Sir / Madam,
What is the size of the Brochure? Do you need it be in A4 single side?

Hello,
I was thinking it would be a double-sided tri-fold, 8.5"x11".
Like a standard piece of paper, print landscape, with three vertical folds.
That was what I imagined, but it could be something different.
Thank you,
Alex
