Hey Larry,

The Micro Dots are acutally made with photographic equipment and is actually film - or at least a section (circular cut) of a piece of film. This is different that the micro printing on the US Currency - it is actually smaller.

The original image I made of the Micro Dot that Don posted below was ~64x. This image has been reduced and I have not recalculated the actual magnification factor.

If you would be interested in seeing the others I have scanned - let me know and I can either put them here - or a URL to their location...
