That's the numbers in a 1980 model C152 POH that I've got in my personal archive. Copying and pasting...

SPEEDS FOR NORMAL OPERATION

Unless otherwise noted, the following speeds are based on maximum weight of 1670 pounds and may be used for any lesser weight.

Takeoff: Normal Climb Out 65-75 KIAS
Short Field Takeoff, Flaps 10°,
Speed at 50 Feet .... 54 KIAS
Climb, Flaps Up: Normal 70-80 KIAS
Best Rate of Climb, Sea Level 67 KIAS
Best Rate of Climb, 10,000 Feet 61 KIAS
Best Angle of Climb, Sea Level thru 10,000 Feet .... 55 KIAS
Landing Approach: Normal Approach, Flaps Up 60-70 KIAS
Normal Approach, Flaps 30° 55-65 KIAS
Short Field Approach, Flaps 30° 54 KIAS
Balked Landing: Maximum Power, Flaps 20° 55 KIAS
Maximum Recommended Turbulent Air Penetration Speed: 1670 Lbs 104 KIAS 1500 Lbs 98 KIAS 1350 Lbs 93 KIAS
Maximum Demonstrated Crosswind Velocity 12 KNOTS
The short field landing performance numbers in the back say they're based upon 54kts at 50ft, for 1670lb, flaps 30.
