Yeah, $1,500 would be a little out of the question (maybe), but the sketches in Paris were in the range of 300 EURO.
I just don't want to buy something out there, but directly from him, so just asking around. Remarks are nice, but they were indeed expensive and, in my opinion, a sketch is so much better. Still, a remark would be nice if he agrees to.
Really depends on the detail of the sketch. I've seen seen a JSC sketch on blanks sell for as high as $2500. Your price point of $300-$400 range for a JSC sketch will be very difficult, not when some remarks are already selling for $1000
