One of the top-selling graduation cards in my studio also happens to be a design that has received the highest number of pins over on Pinterest. The card is from the Billboard Grad Card Collection and while it's an oldie, it's certainly a goodie. I love that we often receive inquiries at the portrait studio from friends and family members of former high school senior clients who have held onto our grad cards as a reminder when it's time to book a session for their child. Graduation cards have been a great source of word of mouth advertising for us!
