help with beaded police helmet please

[chokesalot]

is it real,about what is its value,should i look into possible restoration? it has no liner,a finger painted peace sign on top and a few yellow crayon looking lines. it is marked EF66 ...20706..7. it has classic party/police decals.name inside is"H.Dammann".also if anyone could trace this name i would like to see if the family would like to have it back as its their heritage after all....
