**ULTRA-RARE HOLY GRAIL PHARMACEUTICAL COLLECTIBLE** Up for sale/purchase is an incredibly rare, vintage promotional pharmaceutical coffee mug featuring branding for **Percocet** and **Percodan**. Distributed historically by drug representatives to medical professionals, this is not your standard static ceramic mug—it features a highly sought-after **heat-activated color-change reveal**. **The Interactive Feature:** * **Cold State:** Features a clean white aesthetic with the classic boxed branding, anchored by a solid, dark heat-sensitive block at the bottom.
* **Hot State:** When hot liquid is added, the dark block seamlessly fades away to reveal the historic promotional slogan: *\"CONTROL PAIN. THE SOONER THE BETTER.\"***Collector\'s Note on Rarity:**
While standard vintage pharma mugs appear occasionally, interactive thermochromic \"magic\" mugs from this era are exceptionally scarce. This specific Percocet/Percodan variant is virtually non-existent on the current secondary market, making it a true centerpiece \"grail\" item for serious medical history, oddity, and pharmaceutical memorabilia collectors. **Condition:**
Excellent vintage condition. The ceramic body is clean with no major chips or cracks. Crucially, the sensitive thermal film coating is fully intact and responds to temperature changes (as pictured). Please review all photos carefully to assess cosmetic condition. **Care Instructions:**
To preserve the integrity of the 30+ year-old heat-sensitive coating, **HAND WASH ONLY** with a soft sponge and lukewarm water. **DO NOT** place in a dishwasher or microwave, as high heat and harsh detergents will permanently damage the color-changing effect. *Ships quickly and securely packaged with extra padding to ensure safe delivery.*
