2019 Topps Museum Collection Baseball Forum

I have a 1-of-1 card from this set of Mike Piazza. On the rear it says it is an "ARTIST ORIGINAL CANVAS COLLECTION." It is signed by the artist, Matt Stewart. I don't see Piazza on the checklist for the Canvas Collection Originals. Is this a different insert set or is Piazza missing from that set's checklist? It is not a numbered card, it is only numbered as 1-of-1.
