I have a titling system that I like to use that pre-indicates to artists what the piece I have submitted is - many understand it, but some might not - this is here to help you out!
:CM: - Indicates a COMMISSION piece
:WLR: - Indicates a Wish List Return*
:AT: - Indicates an ART TRADE
:G: - Indicates a GIFT
:ZP: - Indicates a piece featured in a Zine or group project
:.OTA: - Indicates an Offer To Adopt design
- where someone can offer what they choose in order to gain that design
* - A Wish List is typically a list, Amazon List or other accessible list of items or supplies they want or need that someone can buy for them in return for a piece of artwork priced at equal value or stated otherwise.
