One could wear a different t-shirt featuring H.P. Lovecraft or inspired by his works every day for years without repetition.
Cafe Press: Cthulhu t-shirt: 1477 results Lovecraft t-shirt: 1159 results
Zazzle: 746 results Cthulhu t-shirt: 1035 results
Red Bubble: Cthulhu t-shirt: 676 results Lovecraft t-shirt: 801 results
Spreadshirt: Cthulhu t-shirt: 60 results Lovecraft t-shirt: 27 results
In the above, there are some false positives and generally a huge amount of overlap between the two categories.
HP Lovecraft Historical Society: 15 t-shirts
Arkham Bazaar: about 60 t-shirts
T-short Bordello: 8 t-shirts
I could keep going, but you can see the diminishing returns.
So it’s kind of striking that last month Lovecraft Holdings, founded 2009, has filed for a standard character mark for “H.P. Lovecraft” on clothing, including “sweat bands, ear muffs, aprons, scarves, bandanas, belts, suspenders, neckwear, ties, underwear, briefs, bras, socks, robes, underclothes, pajamas, sleepwear, night gowns, nighties, lingerie, hosiery, tights, gloves, mittens, rain slickers”. Just filed, the USPTO hasn’t examined the filing yet.
IP law is a quagmire, so I’m sticking with “striking” rather than so much as speculating on what the consquences would be if it’s granted.
