De sacris aedificiis a Constantino Magno constructis : synopsis historica“, Rar 1279
The cover looks more like a modern artwork rather than a book cover from the past.The pages have different colours to them (one lighter or darker than the other)The edges of the book were orange colored.I choose the first page because it was quite interesting how they had big decorations and lettering.and the second page was this drawing which was on page 9 on google books. But surprisingly, all the drawings were at the back of the book. some were folded since they were too large to fit on an A4 page.
