Re: Question \'bout smallbeads
t-mojo, the great holes of the World may only be a few years old, or up to ten years depending as the stamps were not done all at once. John Houck would probabably know exactly. The other stamp may be a recreation or very old. Compare the underside of each disc to the other. If they look the same, they are probably the same relative vintage. If there is a distinct two concentric ring pattern on the Lavonne disc, it is much older.
By far, the most important part of any shot is what is happening in the last split second as the disc is pulling itself from your grip. Focus there. It's the key.
