Soul Music: Animation Cell from Cosgrove Hall mini series

Animation cel from the Cosgrove Hall mini series of Soul Music. This appears to be part of a desert scene? Maybe from the Klatchian Foreign Legion segment. Size 42 x 30cm approx. Excellent condition. The back story is that Cosgrove Hall were supposed to be at the 1998 Discworld Convention, as they had been in 1996, but couldn't make it, so by way of apology, they sent a stack of animation cels, enough for each attendee to have one. The Committee put them all in envelopes, wrote membership numbers on them, and you went and collected yours. Very rare Discworld collectable .p.
