This huge key pan is from the "Memory Mahjongg" episode of the Nadesico TV series. Akito has gone all heroic, and he and Akatsuki are having a race as they bicycle into the Nadesico's innards to save the day. Izumi, in the back, looks unimpressed as always.

I really like this cel, but unfortunately sometime in its past someone let the two layers stick together while they were mis-aligned. This means that the corridor backdrop (which is actually a cel) is a bit higher than it ought to be with respect to the characters.
