Gary Yamamoto Top: Jumbo Grub, Gary stamp Bottom Left: Jumbo Grub, Gary stamp Bottom Right: Jumbo Grub, no Gary stamp These three show noticeable color transfer. The presence or absence of the stamp likely indicates the year of manufacture. Please check the colors and quantities in the images. These were stored in a box for a bass boat, but are being sold to organize my collection. I don't think there are any hook marks, but please understand that these are used items. Shipping will be via Yu-Packet Post Mini.
