I am not sure if it is Vector Art artwork or not (with over 10K on the market and more coming its hard to check!). There are several collections so it easily could be, or if not ours then someone elses collection.
Unless you know its origin (either that you draw it yourself or the license allows you to share it) then it is probably safest not to post it, as it is likely to belong to someone, somewhere. This is not to try and stop people sharing just to check their source and any related licenses. Thanks, James.
