Collecting all unique artworks(or as many as I can) of a single artist has been one of my favorite ways to collect. Not to mention, it is one of the coolest ways to look at cards in binders.
While completing sets and looking at them in binders is nice, I think that most sets lack cohesion, or a shared theme common throughout every card. That is why I love collecting artists cards, because they all have a shared theme!
Here is a snapshot of my artist collection so far: boogus collection thread . They are at the bottom of my most recent post on this page. So far I collect:
tetsuya koizumi (almost up to date)
Kimiya Masago (completed)
sowsow (almost up to date)
Asako Ito (up to date)
Sachiko Adachi (just started)
I have a lot to say about this topic which is why this post is all over the place. but yeah, I really like these artists
Also, can we talk about tetsuya koizumi? SO slept on. one of the best at giving Pokémon a wide range of emotions, showing great detail in the background and showing Pokémon in their environment. Probably my favorite artist of all time.
