This is a much discussed subject, if you look at page three of the forums (raised about two months ago) you will see a lot of advise and info on that feed on copyright for a frozen cake… I tried to send you the link, but it won’t let me from iPad, maybe someone else can
I personally prefer to not take on these kinds of cakes, and if I do, will share for a brief day or two on my facebook page and then take it down, or on some I don’t share at all and let the client know as well. I Do know Walt Disney have clamped down on quite a few cake friends of mine, they are very clear on copyright , even for charities
You must never limit your challenges, instead you must challenge your limits
