A question about One-Offs and custom content (Patreon)

This kind of a follow up question about doing a quarterly magazine reward based on the MF Sketchbook style of content.

I was think of having maybe 2 or maybe even 3 versions of the magazine. 

1. Standard

2. Same as standard but with a one-off sketch (in the magazine) of my choice. 

3. Same as standard but with a one-off sketch (in the magazine) subject/reference chosen by the patron.

The number of slots for the one-offs would be very limited so maybe only 2 or 3. The sketches aren't shared with other patrons so it's private to the patron.

So the question.

Would you pay for a one of a kind magazine with a sketch or just want a standard one?

(Whatever your answer it is helpful)
