This installment of the Royal Mail Gerry Anderson tribute features a set of four lenticular stamps on a punch-out sheet. This set fits in a clear plastic sleeve attached to a large decorated card (which doesn't show up in the scan) featuring the Thunderbirds team on the front while on the reverse, Brains explains how lenticular stamps work. As cool as the envelope featured in last weeks blog was, I think I like this one much better! Enjoy!
