I thought Panini had started releasing Diamond Kings as a range in itself in the years after the company acquired the rights to various DonRuss ranges. I've now discovered that DonRuss started doing it at the start of the millennium before being swallowed by the Panini empire.
However, the first card in today's post comes from the 90s, when the Diamond King cards were an insert series in the DonRuss flagship set.
Card Number 780: DonRuss, 1994; #DK-11
The cardback also has a handy line up of Tony's Diamond King appearances, which acts like a mini checklist. I will round out the set when I add his 2001 card to my collection!
