Massive objects create dips in spacetime, causing other objects to \"roll\" towards them, while extreme gravity, like near a black hole, severely warps it, affecting time and space dramatically. This '70s style design may reference spacetime, or just be some hippy dippy cosmic crap with stars and rainbows, but who knows?  \u003cimg class=\"alignnone size-full wp-image-608\" src=\"https:\/\/psyne.com\/wp-content\/uploads\/2025\/11\/ebay-spacer-1.png\" alt=\"\" width=\"1275\" height=\"16\"\u003e \u003cstrong\u003eProduct Details\u003c\/strong\u003e\n\n\u003chr\u003e\n\nLike 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.

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. \u003cstrong\u003e\u003cimg class=\"alignnone size-full wp-image-608\" src=\"https:\/\/psyne.com\/wp-content\/uploads\/2025\/11\/ebay-spacer-1.png\" alt=\"\" width=\"1275\" height=\"16\"\u003e\u003c\/strong\u003e\u003cimg class=\"alignnone size-full wp-image-606\" src=\"https:\/\/psyne.com\/wp-content\/uploads\/2025\/11\/ebay-size-chart.png\" alt=\"\" width=\"1275\" height=\"220\"\u003e \u003cem\u003e\u003cstrong\u003e\u003cimg class=\"alignnone size-full wp-image-608\" src=\"https:\/\/psyne.com\/wp-content\/uploads\/2025\/11\/ebay-spacer-1.png\" alt=\"\" width=\"1275\" height=\"16\"\u003e\u003c\/strong\u003eAll sizes are provided in inches!
