I watched some animes when I was a kid like Gigantor, Kimba and Speed Racer and literally got my hands into animation doing clay-mation way back in elementary school. I've always been fascinated by animation art and techniques. Especially things like walk cycles, background loops, long still shots and other techniques used for efficiency.
Fast forward to me being a dad. I often joke that my daughter knew she wanted to be an animator about 15 minutes after she was born. She has always been constantly drawing and painting, and is now an animation major at Laguna College of Art and Design. Pretty much everything they do there is using old-school, 2-D, paper and lightbox techniques. Wonderful, amazing stuff.
She discovered anime at a pretty early age with Full Metal Alchemist being the first she asked me to watch with her. It was great! Then we ramped up with DeathNote, Number 6, Hunter X Hunter, Angel Beats, and on and on... It's been an absolutely wonderful thing to share with her. We even once did a 3 hour road trip to see "Conqueror of Shamballa" in a theater when it first came out. Then we got into cons and buying fan art (we love meeting the artists). And she's sold her own art at a few as well.
Last year, we went to Anime Expo for the first time. And that's where it happened: cels! There was a dealer there with books and books of them and I was immediately, completely hooked. Intellectually, I knew they existed, but to see them up close, and actually be able to buy one? Wow.... My daughter laughed. She said "You have the exact look everyone does when they first discover cels

So, while we aren't rabid collectors (who can be in this day and age, at least in my tax bracket?

Unfortunately, time doesn't wait, so we do most of our anime bonding via text these days ("Dad! What episode are you up to in "Bubblegum Crisis?" "17." "Cool!!!"). But, we watch together when she comes home and are talking about a con or two later this year. We actively try to watch older animes done in traditional 2-D. So we can buy cels

One of the most fun moments in our cel collecting was when she left a "Yu Yu Hakisho" cel with me. I was watching the series (without her, unfortunately) and I sent her a picture of that exact frame on the TV with my hand holding up her cel next to it (in a protective sleeve, of course - lol). She and her friends (all animation majors) lost their minds - they LOVE that show. A dealer we met at Comic-Con told us "Wait until the first time you freeze-frame a show and go 'that's my cel!!!!'" He was SO right - lol
So, we're kind of late to the cel world and it seems that a fair number of collectors are moving on. But, we're just getting started. For old-school animation and art geeks like us, this is the coolest thing ever!
