SPCA is a humanitarian work group that aims to stop human or animal suffering due to cruelty. SPCA has its logo branded on the shirt prominently. It promotes awareness of SPCA and conveys the message to protect animals. It provides free advertising to anyone who see the shirt. It also brands the person who wears it as a supporter of SPCA. This will encourage commitment from others too. Shirts are a great way to convey your marketing messages.
