Playbill inspiration for next prints

Looking at playbills from the 1960's. Playbills were posters announcing the musical or play but there is a magazine subscription called 'Playbill' that is for monthly theatre goers and I think I will base my next prints in inspiration of this. All of the playbill covers from the mid-century are very graphic and feature portraits which I think will look effective along with the poster. 
I will cut the title of Playbill into the print and then I can also photoshop my print onto one of the photos so that it looks more original, I'm aiming to submit my work on the 20th which gives me 18 days to create these prints, I will be able to do around five I think.
