As everyone goes First World War commemoration-crazy (and rightly so), a reminder that you'll find information on the ubiquitous WW1 trio on the following British Army Medals pages:

1914 Star
1914-15 Star
British War Medal
Victory Medal

Also see this post which details dates of issue for the 1914 Star, 1914/15 Star, BWM and VM.

Finally, don't forget the Territorial Force War Medal.

The above information may be helpful in dating photographs of service personnel wearing a single 1914 Star (with or without clasp) or 1914/15 Star; similarly photos of men wearing just the ribbon for these medals.
