thats the thing about collecting, I say it again and again, its the thrill of the chase.
I work in another field, but with collectors, and I tell them over and over, some days a client comes in and because we dont have a certian item theyb get frustrated, I remind them, IF YOU HAD THEM ALL, YOUD PROBABLY SELL THEM.
A good client bought a Mint example of every Sovereign size coin ever minted, we are talking MANY millions of dollars, took 10 years, soon as he finished, he sold the lot. NOW, few years later, he has started again.
If you had $x.. and could buy every poster you ever wanted in one go.
then what do you do?
Collectors enjoy waiting, trying, losing, winning, unpacking, storing, then unless you frame it, or are reminded, its forgotten most of the time.
AGAIN, THRILL OF THE CHASE. (oh and showing off to other collectors online)
