First, you will need to do at least a Google search, words and/or image, to be sure you won’t run into any copyright or trademark issues. You can also search records at the U.S. Patent and Trademark Office online and the Copyright Office online. It may sound silly, but it could end up costing you a lot of time or money if your idea is infringing on someone else’s work.
Cover Verse: Happy Birthday, Daughter If you can laugh often, love deeply, and let the dreams of your heart create your tomorrow... Inside Verse: If, no matter how busy life gets, you can find joy and wonder in the little things and a few quiet moments for yourself... If every day you feel as loved, as beautiful, as celebrated as you do today... Then you'll always know the kind of happiness a daughter like you deserves.
It is traditional, among English-speakers, that at a birthday party, the song "Happy Birthday to You" be sung to the birthday person by the other guests celebrating the birthday. More specifically, the birthday person is traditionally presented with a birthday cake with lit candles, with the number of candles sometimes corresponding to the age of the person. After the song is sung (usually just once), party guests sometimes add wishes like "and many more!" expressing the hope that the birthday person will enjoy a long life. The birthday person may be asked to make a wish ("Make a wish!")—which he or she does silently—and then is supposed to blow out the candles. Traditionally, blowing out the candles is believed (or is considered a lighthearted superstition) to ensure that the wish will come true. Once the candles have been blown out, people may applaud, after which the cake may be served, often with the first piece being served to the person whose birthday it is.
I sell physical prints mostly out of the fear of someone reselling. Like you said, they could still do that with a physical copy by scanning but at least that’s a little more of a hassle. I’d also hate to see my art printed on shitty paper or the colors are completely off because the buyer (or print service they use) doesn’t put in the effort to get the colors just right.
