In case anyone's (who's anyone) is interested, I have a downloadable, lengthy and color illustrated photo identification and dating guide. You can use the guide as is. However, you can also take it as a home study course. The texbook includes homework assignments and you can also take a final test. The guide with homework is free. However, there is a fee if you wish to take the final test and have the homework graded. Anyone who passes will get credit for finishing the course and demonstrating their introductary understanding of the subject. Auctioneers, dealers, historians or whomever may (or may not-- what do I know?) find it beneficial to advertise they passed such a course. Thanks
