In general I experienced that all those people asking if you have prints made... once that you responded affirmative... disappear from your screen as fast as flies from the marmalade pot once that you moved your hand...except Reinhard who prefers to eat the marmalade.
Hehe... I'm sure we all have our stories about oh so interested would be collectors. Alright with me. People buy (or not) art for different reasons. When someone wants it as an investment, they go to what they think is a trusted source... can work (or not). Others simply don't feel the need to own any... instead they go see a soccer game.. everybody should be free to like what they like :-)
For me its plain addiction and I spend most of my money on art or the creation of it (tools and materials)
Ideally, someone should collect art, because of a certain passion for it. If the art is a good investment on top of this, I look at that as a "bonus" 😎
