Hulsroy's Hustle

What you‘re saying reminds me of the Ciavete paint option that Pegoretti offered for his frames:

Each Ciavete is a unique composition, and, as the nature of the artwork suggests, arrives unseen – a complete surprise. However, the Bottega will happily note down your colour likes and dislikes, or any starting point of inspiration you wish to communicate, before starting work. Naturally, there’s a lot of trust involved in handing over complete artistic freedom, which is why the Ciavate scheme, like our painted graphics and panel schemes, is an optional add-on chosen at the time of ordering.

It became a success but I reckon he only got into a position where he was able to offer his work as an artistic package deal because of his stellar reputation as a framebuilder.
