Research
We research dates, prices and product details using primary and well-established sources: manufacturer announcements, contemporary newspaper and magazine coverage, archived catalogs and museum collections. When a fact is disputed (for example, the exact US launch month of a toy) we say so instead of picking one at random.
Values and prices
Collectible values change constantly and depend on condition, packaging and edition. When we mention what an item is "worth", we describe typical ranges seen in completed sales, not asking prices, and we always tell you how to check current values yourself.
Images
Our sticker illustrations are original artwork. We do not use celebrity photos or copy product photography.
Updates and corrections
Every guide shows the date it was last updated. If you find an error, email hello@90strends.com and we will correct it, usually within a few days.
Independence
Brands cannot pay to be included or to change what we write. Read our disclosure for how the site is funded.
