I picked up a copy of Carey Rockwell's 1952 juvenile Stand By For Mars! in a thrift shop recently, and rattled through it in no time at all: hearty if dated fun, enlivened by a bunch of rather nice illustrations. Indeed, these are the sort of pictures that just cry out to be re-captioned. So I offer the book's frontispiece to readers of this blog [click on the image above for a larger version] with this challenge: the best caption in comments below wins the inestimable honour of the title Pyr Blog Thursday Caption Competition Laureate April 2009. So what are you waiting for? (You can see my offering, together with other illustrations from this book, over here).
