Thanks to Colin Laker I now have this very fine and rare piece of Bowman ephemera in my collection.....I am especially fond of this as it has an inscription by GBJ himself (as confirmed by his son Paul, who remembers his father at his desk, inscribing the catalogues with his dip pen and inkwell).

I post reduced-size photos here for the benefit of all interested - feel free to use them in any way you like, except for for profit purposes.
