Random but in case you didn't know Beyblade Burst was animated by OLM Studios which although doesn't use traditional cel animation anymore still uses traditional artwork for story boards and digitally transfers it. (And draws it in a cel style digitally).
Beyblade Burst "cel" art/storyboard sketches have been given away and sold before! I believe I remember there was a giveaway for a few cell arts near Thanksgiving a few years ago (maybe 2 years ago???).
Anyways, my sister actually found a listing for sale a few years ago of Hyde/Hearts from beyblade burst turbo. We split the cost and got it! Here he is, so happy to be able to own a one of a kind, storyboard sketch from OLM Studios of my favorite show and of one of my favorite characters! :D
And here's the clip it was used for! (Episode: #35)
Then about a year after we got it I actually found some more for sale on a Japanese site, I unfortunately didn't have money for them so I wasn't able to get them. There were multiple listings with over 30 storyboards in all. I wish I screenshoted all of them before the bid ended but I unfortunately didn't. Here's some of them that I did screenshot though!
SUOH AND FUBUKI IM SO SAD AGH
