Mayumi Seto. Her name appeared on this blog about two years ago when I got my 2,000th unique Andrew McCutchen card. You can revisit that post here. Since then I've added another 500+ cards to the collection.
Mayumi is most famous for being the artist of Topps The Living Set
As noted a few years ago she also worked on Topps Gallery in 2017.
I purchased the original art used to produce the retail exclusive set.
This is one of three original art production cards I own. Below you can see the card produced from the original artwork above.
There is a few more of these originals out there and I am trying to negotiate to get a 4th.
