You can buy prints of the official group photo from SOC, for several years. It’s a bit tricky: Follow that link to Pixieset, select a photo/year then find the “Open” button in the image, then move your cursor over the image (or click again: it differs between desktop and mobile) to make the shopping-cart icon appear, which takes you to the “Buy” or “Add to cart” page. If the cart icon says “Your cart is empty”, try again somewhere else. Regular prints are available in several sizes and kinds of mounting. Also, a digital download.
