Hi Rowland,
I like this!
As suggested, print it big. And as the wife suggested, on canvas it will look great.
The frames that are effectively borderless, that is they just have a backing to hold
the canvas tight, look fresh and modern and would suit the freshness of the image.
I wouldn't worry about a logo.
Talk to the local printing business and they should be able to provide the best
advice on data format and colour matching, but typically your 8 bit TIFF, if it
is at the original resolution, will be the type of thing most printing houses would
be looking for.
