Guest book in leather covers

44 years ago, a guest book was gifted at a wedding where no one ever wrote anything. Maybe someone needs to forge something and pretend it has a 40+ year old history? Perhaps someone likes the "distressed" aesthetic, where aging has been done by time?
The book's dimensions are 24.5x18x3.5 cm, could be around 200+250 pages (was too lazy to count). Leather covers with small gold accents on the front cover. Completely intact, never used, just old.
