These are the two men suspected of a sexual assault on a pregnant woman in her home.
The attackers left their 20-year-old victim bound, gagged and naked in her Elmina Road house while her eight-month-old daughter was in bed upstairs.
Police believe that the assault, which took place in the early hours of Sunday, is related to drug dealing.
However, the woman who was discovered by her partner is not a drug addict.
Officers are now appealing for anyone who recognises the men in these artist's impressions to come forward.
Senior Investigating Officer, Det Insp James Vaughan, said: "This sickening assault on a young, defenceless woman in the presence of her baby daughter is completely beyond contempt and I urge anyone with information, no matter how small or irrelevant it may seem, to come forward.
"We hope that the cowardly and despicable actions of the two men will prey on someone's conscience and that anyone recognising them will report them to us."
The woman, who was treated for a minor head injury, was discovered at 4.30am on Sunday.
She is receiving support from specially trained officers and has given a good description of her attackers.
The first suspect covered his face with crepe bandages and has a stammer. He is said to be 6ft tall and skinny. His hair was tied back in a cloth band commonly known as a Doorag, on top of which he wore a baseball cap.
The second man is about 5ft 5ins tall and had a strong West Indian accent. He wore a balaclava-like mask and is described as having distinctive eyes which seemed to be different colours.
Police are currently pursing several lines of enquiry after carrying out a forensic examination of the house and the surrounding area.
Anyone with information is asked to contact the Operation Detain incident room at Westlea Police Station on 01793 528111 or Crimestoppers on 0800 555111.
Alternatively if you have any information on drug dealing, call the Advertiser backed Swindon Drugs Hotline on 01793 528800.
