IVA (Intra-Vehicular Activity) 'spacewalk' inside the orbital workshop of Skylab during SL-4 (Skylab 3) showing an astronaut inside his pressure suit testing out the manned manoeuvring unit. Technically this isn't a full IVA as the room is still pressurised as can be seen by the other crew mate dressed in his regular flight tunic.
