We did have something similar when we were kids. It was not called Top Trumps but it was a package of cards with cool old cars and their stats. Maybe it was just meant to be a collection but me and my sister, we played it as a game, exactly like you played Top Trumps :) If only I knew where those cards are now. They might be worth a fortune at some point in future :)

Should I check?
What you had is most likely your country's version of top trumps, for sure. The original company licensed other companies to sell the game. Get some to play with Flora xDD
