The paintings are probably not worth the price you recently paid for them (in my opinion).

However, in the future they might sell for millions of euros. That's just how art investing goes. It's impossible to predict what will sell in the future.

I saw a story last year where the famous guitarist Eric Clapton sold a 'painting' (which looked like someone who was drunk just threw paint buckets on the canvas and called it 'art') for Millions of euros.
