Foil, virgin, dual: three objects, one issue

Print shops taught collectors that an incentive cover is a different object from the newsstand look. Marvel NFT comics inherited the same problem with new vocabulary: foil overlays, virgin treatments, wraparounds, and dual-cover files that show a back image as soon as you scroll.

If those treatments share one spreadsheet row, a later reader thinks the collector is repeating themselves. They are not. They are holding three visual objects that happen to share an issue numeral. Utility Flow Core’s variant desk writes STD, FOIL, VIR, and DUAL as studio codes. They are not publisher SKUs. They are filing marks.

A foil overlay is visible or it is not. We do not mark FOIL because a listing description used the word “shiny”. We mark FOIL when the file shows a metallic treatment. Collectors sometimes photograph a screen at an angle that creates glare. Glare is not foil. The remark column exists for “possible glare, check again”.

Dual-cover files need a note about the back image. If the back is blank, it is not dual. If the back continues the scene, it is dual even when a marketplace thumbnail only shows the front. Cataloguing from thumbnails alone is how dual covers vanish.

This is still not authentication. We are describing what is on the image you supplied. A publisher could use different house names for the same look. Our codes stay boring on purpose so a desktop catalog remains sortable ten months later.
