First, I do like to have the entire run of gengas and/or dougas in CGI sketch sets and dislike it when owners/dealers break them up for individual sale, as if the dougas were like individual cels. When I've been able to, I've gotten and maintained these groups as sets.
However, in the case of series of cels, I'm not terribly anxious to get sequence-mates for most series. In fact, if I get two cels from the same sequence, I'm more apt than not to dispose of the one I like less. But there are exceptions:
- 1. When cels from the bank where (Cardcaptor) Sakura captures The Fly Card in Ep. 1 where plentiful and cheap, I bought up a dozen of them and made a gallery out of them. Unfortunately, people realized that I was collecting them and did rather mean things when they came up for auction, which meant, I guess, that the apparent value of the cels I already had got automatically increased about fourfold. (Meh, a dozen from this cut is enough, anyhow.)
2. When Vapalla got a wonderful "smiling Raphael" from the last episode of Tenshi ni Narumon, she traded one to me from earlier in the cut. But I loved hers so much that when a sequence-mate like hers came up, I bought it and kept both of them. (Happily, I also got a cel of Natsumi from the little cut that was inserted into the middle of the Raph sequence, so actually I ended up with a nice little anime tripych.)
3. I have four cels from the great piggy henshin from Tonde Buurin and am not likely to get rid of any yet. (Ai to yuuki no Pig Girl Roorock!)
4. I also have three sequence-mates plus a test cel from an especially dramatic cut where (CC) Sakura uses The Sword.
5. Overall, if I can find cels that go with series of gengas that I already have, I'm more apt to get them to reunite them with the related production art than if I simply have a related cel.
6. In several cases mixed batches of cels have come through the same jobber, who made up lots by picking cels from the same stacks over and over. This is true of Tennimon and Tree of Palme as well, where even before the 93-cel wonder I'd managed to put together little runs of 2 or 3 from the same cut.
