Every family knows the grandpa formula: hand out the treats, then hand back the kids. A grinning grandpa walrus in a cardigan passes two hyper walrus kids back over a garden fence to a weary parent, the little ones still clutching lollipops and cookies. The retro faded screen print in navy, red and cream gives the joke a warm, vintage feel.
Grown kids buy it for the grandpa who spoils the grandkids and sends them home buzzing, perfect for Christmas, his birthday or Grandparents Day. It is a fun everyday tee for backyard visits, family dinners and the drive home after a sugar-filled weekend.
