About This Design
Christmas Joy Proven By Penguin Math T-Shirt
Christmas Joy: Scientifically Proven! This unique and humorous design is the perfect equation for holiday cheer and clever humor. It presents The Unified Field Theory of Joy, humorously demonstrating that the festive outcome (\text{Christmas}) is derived from the core \text{Penguin} variable. The graphic is a detailed chalkboard illustration featuring a cute penguin in a Santa hat, surrounded by academic diagrams and the final Q.E.D. conclusion. It’s an ideal choice for STEM enthusiasts, physicists, math teachers, or anyone who believes that logic and an adorable penguin are the true keys to holiday happiness.

Basic Dark T-Shirt, Navy Blue, Adult S
I found the shirt quality itself to be well made. Unfortunately I found that the image quality of the artwork is low resoultion. So the art and words aren't as clear. I probably wont buy another shirt to be honest, but I'm glad I supported the podcast of which I'm a fan of. I was just hoping that for the price I paid, it would have been of better quality.

this was good quality and perfect colour. Printing was great although when we all opened our secret santa gifts one of the other mechanics commented whoever got that for him missed out part time after the word mechanic
Sorry I don't have any photos

Being a gift I was apprehensive regarding Quality size printing and delivery on time
I need not have worried. Colour was perfect true to the photo and ex quality Being a heavier weight the t shirt probably more suitable for New Zealand’s Autumn and Winter
Excellent printing quality
