Many years ago, when I was but a callow youth, I designed a few posters for Portents, the Portsmouth Poly entertainment team. This one was one of the first and now it's fetched up on the wall of the Victoria and Albert Museum! I've emailed them about getting an attribution as it's catalogued as 'artist unknown', so I'll wait and see how that pans out but I'm still over the moon about it and every now and then I'll think (or even exclaim out loud) "I'm in the V&A!" - it's quite a feeling and something I'm inordinately proud of.
Anyway, pictures below and the catalogue link is here:
