RITCHIE BLACKMORE- Speed King guitar pick- Japan guitar pick

This is an older Ritchie Blackmore Speed King pick that was made by Pickboy in Japan in the mid '70's and very rare in this new/old stock condition. This pick is part of a collection that was discovered recently in Japan in a warehouse and is in mint condition. An unusual find for a pick around 50 years old. It is an extra heavy gauge pick. I'm a reliable seller with a track record of 100% positive feedback for over 25 years. Thanks for looking.
