Michael,
Nice To hear from you.
If you go onto my Website www.cardguardgallery.com go to the 'Filter The Card Guards By' Panel and in the 'Title/Keyword' Box type Button and then hit the 'Submit' (at bottom of panel and you will see all the Dealer Buttons.
The Dealer Button is normally Large, and placed in front of the Poker Player by the Croupier, acting as the 'Dealer'. It moves around the table in a Clockwise manner, as each hand is dealt.
Hoping this helps.
Gerald
