The walls are decorated with original advertising posters, including those from the famous "Think Different" campaign from 1997 featuring images of Bob Dylan, Pablo Picasso and Albert Einstein.
Lupina said he started collecting "just for the pleasure of seeing them" and because the products would previously have been "too expensive for a resident of post-Communist Europe".
After some time, the collection began taking over his house on the outskirts of Warsaw -- starting with his office and then the living room.
"I sold the furniture in the living room, the table, the chairs and I just left some armchairs," he said.
In 2017, he turned his house into a museum. When he ran out of space, he found fresh premises and the new museum opened last weekend.
Lupina spent all his free time on the collection, sometimes passing entire nights following online auctions happening in different parts of the world.
It is a costly hobby, he said, adding: "I don't have any savings or a pension, just my collection."
