The signatures I’ve seen on Soundwave Art have always been of a high standard and they come on more of a canvas style rather than paper/card print.
Pricing is consistent or a little lower than other limited items (such as the genesis publications) that have his signature.
So pros for going for this are signature will be nice and bold, pricing is okay and it goes to support the Nordoff Robbins music therapy. Downside it’s a big print if the image doesn’t inspire you.
