Frisbee—No Mold—Red—No Wham-O—Pat. Pend
Disc Color: Red
Lettering/Hot Stamp: Frisbee—Raised outline letters on top; usual "Flat Flip" script on bottom w/ Pat. Pend.
Period of Manufacture:
Special Notes: Height of bottom script is unevenly molded, exclamation point after "Experiment" is too large & italicized looking like an afterthought. Nipples top & bottom are smooth bumps instead of usual cut off sprue on top. No Wham-O or "Regular" on top.
