I went with vinyl stickers. I found austin sticker company via etsy:
https://www.etsy.com/shop/AustinStickerCompanyThey can do 3 color vinyl 'stickers' that act/feel like a vendor did it. Also, they charge per 'sticker' - around $8.00 depending on detail. On that, they can't do fine detail....but maybe send them what you are interested in and see what they can do.
Just noticed they are taking a break so may not work for you if needed soon.
I attached what they did for me.
Later today or tomorrow, I will post up a pic of what their stuff looks like before attaching.
