Sam Haskins was a huge Milton Glaser fan. He subscribed to the ‘Push Pin Graphic‘ (a design newsletter produced by Milton Glaser and Seymour Chwast) way back in the days of his Johannesburg studio and from the time Sam set up his London studio in 1968 he had Milton Glaser art on the walls. Glaser images are still hanging in the house to this day. Sam would have been tickled to see his portraits of Glaser being used by graniph for their collaboration project with the legendary NY designer and illustrator.
There are several other classic designs in the range of t-shirts launched today by graniph. You can find details here.
