LONDON (AP) — Britain's Prince George gets a boost in a photo for a new British stamp set — thanks to some foam blocks and duct tape.

The toddler prince is pictured alongside his father Prince William, grandfather Prince Charles and great-grandmother Queen Elizabeth II in stamps issued to mark the queen's 90th birthday on Thursday.

The adults are seated, but a smiling George stands atop four foam blocks secured with tape so that his head is at roughly the same height as the others. The blocks can't be seen on the stamp, but a full-length version of the image by photographer Ranald Mackechnie was released by the Royal Mail on Wednesday.

The group photograph has been issued as a sheet that divides into four stamps, one for each of the royals.
