I have always found picture frames useful in artwork, either for websites to use around images, or in print to bring attention to certain image or text.
Collecting old vintage out of print catalogs, I came across illustrated gilt frames and gilt mirrors. A selection of these have been made into vectors, so you can edit and colour these to your use – whether to make a vintage effect frame, Gallery or a modern bold effect.
