Chris SPROUSE; Superboy and the LSH unpublished cover

Okay, technically this piece isn't exactly "unpublished" as it appeared in Spectrum #9 (a magazine covering science fiction and fantasy media) where it accompanied an excellent interview with the artist.

Isn't it terrific-!? Beyond just being a ton of fun, there are many of the elements that distinguish a Sprouse cover including beautiful heroes, cool ships and a fully-realized futuristic cityscape. Note the checkered "taxis" flying below.
