personally I think its an odd choice for a credit union. why not go with a simple blue or green card. why have a father and son on a card ? not all families are white with a golden retriever. In this day of diversity and acceptance (some people don't have or want kids) seems like an odd card to give all your credit card holders.
I think they have two other designs. One of them is a United jet, like the ones on their checks. I forgot what the third one was. I think these other offers only appear if you apply with the online form for the card after you have already been a customer.
