Apologies if this has been asked or posted already (I couldn't see it if it has) but is there a comprehensive list that covers all variant covers (including retailer exclusives) for each issue of 'Alien' since Marvel took over? I know they went crazy and almost every issue has variants, but I keep seeing more and more covers I hadn't seen before whilst scrolling eBay. Does anyone know if there is a comprehensive list with images out there? (You know, in case I'm crazy enough to start the endeavour of collecting them all)? 😁
