The reason why I don’t recommend before people have kittens is due to the fact prices on Ebay are not correct. The price for thrashed prints are 10x the value in some cases. Can you get lucky? Sure… But the way to get titles is basically by trading for other titles. Also for ones who want to rent prints. Again I don’t recommend it becomes pricey.
The key is go on market place be willing to travel & do as much buying in the wild, get a strong 4 or 5 titles & start trading with other collectors… best way… anyways good luck… if you need help let me know…
