I recall "pulling" these from retail repacks back in the early '00s than had the typical "Find one auto or memorabilia per box!" tag line. Most assuredly a secondary market distribution, after the fall of Score Board. Never got the big names (like Duncan), but they are nicely designed & well-inked autograph cards - unlike the sticker scribbles from today's products.
I added the bold for emphasis on why these are not listed and won't be.
