“Double the party, double the fun, join us to surprise them at a double header birthday game!” This baseball photo invitation hits a home run for your party! For a daddy & son team birthday invitation, we included two cute photos for their joint birthday event and accented them with a baseball and bat. You can use any of the themed phrases on this example or use any baseball phrasings you prefer. We can also change the graphics for a different sport and match the colors to favorite team colors.
