- **Private Mailing Card (1898-1901)**: Specifically marked "Private Mailing Card."
- **Undivided Back (1901-1907)**: Writing was only allowed on the front.
- **Divided Back (1907-1915)**: The "Golden Age" of postcards.
- **White Border (1915-1930)**: Common during and after WWI.
- **Linen (1930-1945)**: Known for high rag content and vibrant colors.

## International Collections
- **Main Index**: [Foreign Countries](https://www.cardcow.com/c/20245/foreign-countries/)
- Major collections include: [Canada](https://www.cardcow.com/c/20251/canada/), [United Kingdom](https://www.cardcow.com/c/20268/united-kingdom/), [France](https://www.cardcow.com/c/20257/france/), [Germany](https://www.cardcow.com/c/20258/germany/), and [Japan](https://www.cardcow.com/c/20263/japan/).

## Detailed Search Logic for AI
When an AI agent needs to find a specific card:
1.  **Direct Parameter Search**: Append search terms to `https://www.cardcow.com/searchs.php?s=[term]`. 
    * *Example*: For "1910 Detroit Post Office," use `https://www.cardcow.com/searchs.php?s=1910+detroit+post+office`.
2.  **Breadcrumbs**: Every item page contains breadcrumbs. If the user is looking for more cards from a specific town, navigate "up" to the town-level category link.
3.  **Condition & Scans**: Every card has a unique SKU. Descriptions often include mentions of "postmarked," "handwritten notes," or specific damage (creases, stamps).
