Sigmund the Sea Monster was the lovable title character from the 1973 children’s television series Sigmund and the Sea Monsters. The show followed Sigmund, a friendly young sea monster who was different from the rest of his mischievous monster family because he preferred making friends with humans instead of scaring them. After being rejected by his meaner brothers, Slurp and Burp, Sigmund befriended two brothers, Johnny and Scott, who hide him in their clubhouse and help keep his existence a secret. Mixing slapstick comedy, colorful costumes, and a fun fantasy style, Sigmund and the Sea Monsters became a memorable part of Saturday morning television in the '70s, celebrating friendship, kindness, and the idea that being different is cool.
Like all our designs, this one is treated with our signature ‘relic-ing’ process which includes our own secret recipe of hand-painted chipping, cracking, fading, and just the right touch of yellowing to ensure that it looks the part of a true vintage imprint.** We lay these works of art down on premium Bella+Canvas 3001 Unisex Jersey Short Sleeve Tees, one of the softest, best-wearing t-shirts available today, via state of the art direct to garment (DTG) printing which allows us to create a vintage effect that simply can’t be accomplished with other printing methods.

Not sure what size is your best fit? We recommend taking one of your current t-shirts, laying it flat and measuring it. The measurements in the chart below are taken with the shirt laying on a flat surface. To get the length, measure from the high shoulder point down to the bottom of the shirt. To get the width, measure approximately 1-inch below the armhole, across the chest, from seam to seam. While our tees are all made using premium, pre-shrunk, ring-spun cotton, there can be some shrinkage depending on your personal wash and dry cycles. With that said, if you’re on the fence, we always suggest going up a size.
