These are small DrawFile 'thumbnails' are taken from high-quality sprites.
If you would like the full versions of these Sprites, see the details with
each file.

There are other 'thumbnails' of Roger/John and general Queen images as well
as some other Brian/Cross and fans illustrations. I can supply a disc full
of thumbnails of my whole Queen-related high quality Sprite collection for
1.50 (or 2 discs if you live outside the UK. OR a HD 1.6M disc is OK)

The reason for these thumbnails is to display lots of images, albeit at low
quality, so they only take up a fraction of the discs space like this.
