Selection of decks of cards
A fairly common practice is when some kind of deck is taken and the faces drawn in it are removed and photographs of real people are substituted, in this case the workers of the printing house. The deck was presented to guests and customers as a sample of printed products.
Like all free promotional decks - now a rarity.
