Probably manufactured by AP as early as the 30s to as late as the 60s. Because there are no natural jokers, all eight tiles used for jokers are stickered. Flower tiles from this manufacturer (or TYL) have no numbers. The one bam is often referred to as 'corn cob'. There are 152 tiles only and are packaged in an unlidded Lucite box w​/​yellow dice. This set is in excellent condition and has been used recently for American play. No flea bites or damages. Why do I want to sell this collectible set? As my collection of sets continues to grow, I have chosen to rehome a few. Or buy a bigger house. Not practical.
