Claddagh  is a traditional Irish symbol in which a heart represents love, the crown stands for loyalty, and two clasped hands symbolize friendship. 
This comes on a card with the sentiment on the card still rings true. ( Surface dirt on the back)
St Patrick's day.
"The top o' the mornin to you and may this shamrock bring you Good Luck!"
Great accessory for any traditionally Irish holidays or futbol matches.
