About This Design

Persevere (by physicist Max Planck) T-Shirt

Persevere (by physicist Max Planck) T-Shirt

By now we've all seen the famous British poster exhorting us to Keep Calm and Carry On. Apparently eminent physicist Max Planck did too, and he wrote his own geeky version aimed at his fellow scientists (we're not kidding, for once). The wording is a little stiff, and very much spoken like a sensible, straightforward kind of thinker, he wants us to continue working. Wear it to a picnic! Wear it to the moon! The circumstances of the slogan's creation are not amusing, but maybe we can wear it (literally) a bit more lightly now.

They turned out exactly as we had hoped and we looked good even when we didn't bowl well. The printing was perfect and you can only see 9 pins on the shirt(the 5 pin hidden behind the headpin) which worked for us as we bowled in a 9 pin No-Tap league.

Great t-shirt!!! Quality is amazing and the colours are vibrant. Exactly how described!!! Can’t wait for my daughter to ask and give it to her confirmation sponsor. It’s also came earlier than I expected. Colours were exactly what I expected. The quality is amazing. The images couldn’t be any better. I’m very happy with his product and highly recommend it.

The shirt I ordered was too small. I contacted Zazzle and they replaced it with a larger size. Very happy. .
