AI Item Analysis

This is a standard-sized American comic book published by Marvel Comics with a cover date of August 1991. The issue is notable for being written and illustrated by Todd McFarlane, whose signature style is evident in the dynamic, contorted posing of the character and the highly detailed, 'spaghetti' style webbing. The cover features Spider-Man in his black symbiote-style costume, surrounded by purple-hued webs crawlng with small red spiders. Text on the cover identifies this as the '13th All-New Collector's Item Issue!' and the start of the 'Sub-City' story arc, part one of two. The price is listed at $1.75 US. Physically, the comic is housed in a protective plastic sleeve with a cardboard backing board. Visible condition notes include some light blunting to the corners, particularly the top right, and minor spine stress marks. There is a small white circular mark or sticker residue near the 'M' in the 'Spider-Man' title. The colors remain vibrant with no significant fading. This issue represents a key period in early 1990s comic book history, reflecting the 'artist-as-superstar' era that led to the founding of Image Comics. The craftsmanship is typical of high-volume copper age publishing, using newsprint-quality interior pages and a glossier cover stock.

AI Appraisal Report

I have examined the digital representation of Spider-Man #13 (1991). This issue is a significant artifact of the 'Copper Age,' marking the beginning of the 'Sub-City' arc and showcasing Todd McFarlane’s influential 'spaghetti webbing' and black-suit aesthetic. Based on the provided imagery, the book appears to be an authentic 'Newsstand' or 'Direct Edition' printing. My visual inspection notes a vibrant cover with strong color registration. However, I observed light corner blunting at the top right, minor spine stress (color-breaking ticks), and a distinct white residue mark near the title logo. I would estimate the raw condition to be in the Very Fine (VF/8.0) range. Market conditions for early 90s Spider-Man titles are influenced by high circulation numbers; millions of copies were produced, making this a common find rather than a rarity. Value is driven primarily by the 'McFarlane' branding. Comparable sales for raw copies in similar mid-to-high grade condition consistently fall between $15 and $25. A specimen professionally graded by CGC or CBCS at 9.8 could command $100+, but the noted defects on this copy likely preclude that tier. Limitations: This appraisal is based on low-resolution digital images. I cannot inspect interior page quality for 'browning' or 'foxing,' nor can I verify the integrity of the centerfold and staples. A full authentication would require a physical examination to check for restoration (such as color touch-ups or cleaning) and to confirm the page quality via the Overstreet grading scale. Provenance is not required for this era of mass-produced media, but physical handling is essential to rule out structural defects not visible in photos.
